The Bruce site is below the collapse cliff. The windmills are on the top. You just have to look at the old air photos to see this. Since the lake is just at this level, all the caves are filled up. The karst topography is caused by deep dissolution of soft rocks, such as salt and gypsum. The weakness allowing the water ingress, is caused by the Grenville Front, one of the many megathrusts of southern Ontario.

The shotcrete adds extra weight to pull the roof, without the added stability of an arching action. Note that the overbreak has always had a slight offset, as if the tunnel were intersecting the principle horizontal stress at an angle. I found this to be bizarre, since we always measured nearly uniform stresses in the Paleozoic, and only strong NE polarity in the granitic basement. Perhaps the stress is much great than I imagined? I sure wish there had been pictures for the failure, since this would tell us more about the stress than anything.

These readers support epub, which is an open standard. The nasty-bugger Kindle does not support open standards, and you are forced to buy books from them. What I have discovered is that I can now check out books from the Toronto Library. I don't have to steal them anymore!
You need to have your old crappy xp machine around, since all this drm crap is Windows. You run Adobe digital editions to transfer the borrowed books to the sony. You have a lending period of 21 days, and you can return early, but you get a limit of 10 books!
The more people do this, the more electronic versions of books they buy!
When I wrote Niagara Disaster, I was always worried about the lining. How were they going to do it? As we recall, with Niagara rock, we don't want to put in a stiff lining, until the rock has completely relaxed. So now I have found out, since they have started the Over-break Shotcrete Carrier.
This beautiful machine trundles along with a template, and allows them to paste over the over-break with layers of shotcrete. You can see the arc at the top which tells them how far to go. Shotcrete can only be placed in layers, so the 10 foot overbreak might take a long time to fill in. Looks like no room for rockbolts, so they are merely adhering to the existing layers, adding a bit more pressure to fall.
Look at the bottom (invert). This is the final thickness of their baby-smooth concrete lining. All water tunnels need to be smooth, and fairly straight, which keeps the flow laminar. The final lining matches this thickness, and will also be smooth.
And here's the beast for the final lining!
A classic slip form. That is why the shotcrete lining has to be nearly smooth, and this will put in the thick concrete lining. They will most likely be installing a rebar cage, but I don't know.
And now for something completely different.
This is a random shot somewhere in the tunnel, maybe the repaired section. My eye went immediately to the lower left where we see a spall. OOOOhhh! Is it a stress spall?

I was wondering if they'd ever get something out of the Parkfield science extravaganza. This latest tidbit comes from the 600 m deep seismometer array. Seems that there is a deep rumble that is sensitive to earth tides, and this has to be associated with pockets of fluid. The reasoning, of course, is that pockets of fluid can be extremely sensitive to slight changes in the local combined stress.
This pocket of fluid, trapped in rock can gather volumetric strain, and produce a significant effect at the narrow mouth. A classic effect is a Whistling Cave, where slight changes in air pressure cause strong winds at the entrance.
The rumbling at 15 km depth probably doesn't mean much to the real world of earthquakes.

I'm doing this to pump up my visits, and my ad clicks (nothing!). :)
Still, this is the 'final battle' in the mobile internet wars. I'm not including MS, which is out of it right now. We're talking massive email systems here! When the googy-phone and unlimited data plans become available, Blackberry better have their act together to hold the corporate market, but they have the advantage of clinging to MS, who dominates corporations.
This is an interesting Christmas gift for me. The rise of the corpo-gov blog in Canada. As we know, our lives in Canada are dominated by cartels and self-similar institute-cracies. Normally, you'll never see any brains from these, they just like to fill the wrong tanks at nuclear plants.
But, perhaps some people are realizing this? Did some hero kill themselves to bring out a blog in BC? It's bland, but the editor seems to have brains. I wish them luck!

Journalists across Canada, as well as bloggers, can now use the defence of "responsible communication on matters of public interest" as a defence against libel.
Yeah! We can thank Conrad for this. Any implication that he might be a crook was squashed by vicious lawyers. This might give the timid media a bit of courage....

The Basel criminal court said it acquitted Markus Haering because he had not deliberately damaged properties or acted carelessly on the heat mining project, which aimed to be the first to generate power commercially by boiling water on rocks three miles underground.
Yeah, he won't be burned at the stake! It looked dicey for a while, but they never did catch him throwing the newt eyes down the hole, so he's free for Christmas!
Shut down the attempt to bury waste in the Geological Armpit of the World (Bruce). Sell AECL to China for a buck, and start cleaning up Chalk River (probably worse than Hanford!) Set up the Geofish Nuclear Research Institute at Port Hope. Put in a nuclear reactor for the high-speed electric trains connecting it to Montreal and Toronto (only stops!). Throw in billions to find a way to get cheap neutrons for Canada, by solving the Maple New Physics Issue. Use the neutrons to burn old nuclear waste, which we would temporarily store in a giant underground nuclear warehouse, and make nuclear isotopes. Bulldoze any vegetative Hopians who object.
Set up the Geofish Seismic Research Institute. Retire all those tired Emergency Measures people. Instrument all the eastern seismic zones to show they are all Sisters in Seismicity. Whap all those nuclear people on the jewels to get them ready for an earthquake. Be more aware of soft soils.
Set up the Geofish Geological Institute. Do a full 3-D representation of the crust in the east down to the Moho. Figure out what it means.
I did more research, and I used browsershots.org.
It could not connect. I wrote and said I would be much happier if they said they tested it with anything other than MS, but again I got the same answer. All their quality control depends on complaints! I've been told this type of story a zillion times, and I'm usually right! It takes a long time for others to complain.
So, for my Christmas gift, I want somebody who knows these protocols to tell the president what they screwed up. It is also, probably, bad security, to follow ms shortcuts.
On the other hand, it could be bugs in my latest unstable upgrade, but that's no fun. :)

Yeah, our problems are solved! China will buy candu for a buck, and all those old guys will get nice trips to see the Great Wall! Then, we can buy a candu from China! Hope we can sell OPG to them, as well.....
Thursday, December 17, 2009
OTTAWA (Reuters) - Canada put its Candu nuclear division up for sale on Thursday, saying the operation needed outside investors to boost its chances for growth at a time of expanding nuclear power generation and also help cut the cost to taxpayers.
Hey, maybe this is actually the real thing! The carcass is to be rendered and sold for parts! I suppose somebody will give more than a buck, if there is a big package slipped under the table.
Most likely GE buys it, just for the existing upgrade business, like botching up Pt. Lepreau. Who knows?

Plimer went off at a tangent, starting to list the numbers and kinds of submarine volcanoes. This, I soon found, was a characteristic tactic: when faced with a tricky situation, he starts throwing out random facts.
Doddering old scientists cannot face attack-lawyers (equivalent) on television. Why do both sides want to produce dramatic sound bites? By definition, a soundbite cannot survive a lawyer-type attack. Volcanoes have produced a lot more carbon - in the past - than we do now, and I think this got all mucked up. I did something on the carbon cycle.
Anyway I wouldn't touch all this with a 10 foot carbon-fiber pole!

Environmental groups, however, hailed the lack of public subsidies as "the final nail in the nuclear energy coffin" in Alberta, while concerned residents insisted the government didn't heed their concerns.
Cagey old Alberta - opening the door, and yanking away the Halloween treat! Well, we can forget about them now....
"We believe we pretty much know how to keep a building standing," said Ian Buckle, director of the center's Large Scale Structures Laboratory. "Now, it's the contents of a building that's the next challenge. It opens up a whole new arena for us."
This is a 6-axis shake table, which will be cute to run, since nobody installs 6-axis accelerometers! Still, this is funny. Many times I have said to people: "Don't put heavy things over your bed!" I once saw a bedroom near Ottawa, on the bouncy Leda clay. It had the most deadly, heavy, pointy trophies, on a shelf, right over the kid's bed. I told them, and they thought I was weird....
Monday, December 14, 2009
I almost wanted to skip this, just like the neighbouring 'tweet' article, but, what the hey! I was just surprised at the cost - $4000, which they described as 'cheap'.
People have been working on cheap accelerometers for houses, for years. There's that one project that uses laptop accelerometers. Are any of these things better than tweets? I think not.
For a seismometer to be of any use, it has to be calibrated. Throwing it into a garage usual means terrible foundation conditions. Can they record minor seismicity long enough to see how the site responds? Maybe, with the big-bucks thing, but at that price I still think it's better to install something nicer.
Isn't this the cutest thing? Now, the same media that reported the Tilapia Fallacy, will now go shrill on how Yellowstone will soon blow up.
This brings up the Hotspot Controversy, of which I have written. Mainly, how deep do these suckers go? But this hotspot is almost sheared off. A fresh plume would be rising vertically. This hotspot, sir, is dead. It has met its Maker, it is no longer among the living!
I was bitching the other day on how you can't get any bandwidth in Canada, and how this would destroy us. Well, the buzz among the brilliant young people (my son :) is that Glob-alive will be offering an unlimited data plan for a reasonable price. This immediately destroys the voice cartel, since you can now use Google talk on a Google phone! These young people are busy organizing the world, and the cartel was severely crimping them.
Right now, all our bandwidth has been crimped to support long-distance charges, which is where they get all their money. For the past 10 years, there has never been a need to charge for long distance, since, once internally digitized, there is no extra cost. Now, everything will be digitized at the input.
I have no love for the cartel, may they rot in hell. Now, on to the other cartels!

It's "very unlikely" that a meteor or asteroid colliding with the Earth caused an abrupt climate change leading to the extinction of the woolly mammoth and other large mammals 13,000 years ago, says the University of Hawaii at Manoa leader of a team that investigated the theory.
They were wiped out by a lack of carbon dioxide!
Saturday, December 12, 2009
Because Stephen McIntyre is an enemy of climate change believers, a man who, essentially, double-checks the math behind research accepted as green gospel.
In my good moods, I'd love to be like this! But then I curl up into a ball! He just checks the math, but nobody does the physics!
For me to get that type of traffic, we need the Toronto Earthquake! :)
The project’s apparent collapse comes a day after Swiss government officials permanently shut down a similar project in Basel, because of the damaging earthquakes it produced in 2006 and 2007.
At least they aren't going to pillory the project geologist! Good grief, what do geologists know about rock mechanics?
Obviously the next geothermal project should be right on the Hamilton fault! Lots of potential energy there.... Seriously, if water is the driving element of all 'internal' earthquakes, then we'll probably get earthquakes with most of these 'hot, dry rock' geothermal attempts.

Albertans will finally find out next month whether their energy-rich province will kick-start Canada's so-called nuclear renaissance.
Ha! They are waiting to give approval to a wild dream. There is no way that bankrupt Alberta can go ahead with a nuclear station in the middle of nowhere, even if it does make the oil sands less dirty. People may have to realize that our constant problem with nuclear has been to find the talent. For the 40-50's we robbed Europe. For the 70's we robbed India, and in the 80's we sucked out China (they've all gone back!). Now, even if we can get drunken Russians (or Romanians), they are not going to Alberta!
Even now, it is absolutely hideous to work at OPG's Factory Engineering buildings. Only the truly dying will go there. And Chalk River, the Seismic Death Trap? They're all just the living dead. :)
Now, if we want a nuclear business, we should gather our pennies, and put a billion or two in a giant research facility, right by the Toyota factory (or Port Hope). Put in some high-speed trains to Toronto and Montreal, so people don't feel desolate. Let a thousand intellects bloom!
But they might be surprised to learn that nuclear medicine in the United States is dependent on one 52-year-old, leak-prone nuclear reactor that is currently offline, should have been shut down for safety reasons a decade ago, and moreover, undermines international nuclear nonproliferation goals.
Why doesn't anybody add that it's a Seismic Death Trap? Anyway, this weird article goes on to state that nasty Canada sweet-talked the US into doing nothing about isotopes. But really, the US couldn't build anything major like a reactor, unless the pork could span all states. And that is difficult to do!
This is a most amazing story. They have broken, not one, but two TBM's, in the same manner, and in the same place!
Because of high groundwater pressure and soft soils in the deep tunnel route, officials decided to use a new kind of machine rarely used in the United States. The machine pumps a liquid slurry in front of its cutting blades and then sends a mix of slurry and dirt through pipes to the surface.
Now they are trying to tack on some welds. The darn things are just going to break again, since they don't know what broke them in the first place. Judging by the conditions, and the depth (320 feet!), they have gone way beyond the Niagara Tunnel in adventurism. I wish them luck.

The project designer and geologist, Markus Haering, has been charged with property damage and will have to stand trial in a Basel court next week. He could be sentenced to up to five years in prison.
I suppose they will put him into the stocks and throw rotten fruit at him. Alas, I have nothing funny to say about this, since my blog is dying.
CLARINGTON -- A proposed 240,000-square-foot Ontario Power Generation office building has cleared the next Municipal hurdle, but until new nuclear reactors here get the go-ahead, the office's construction is on hold.
Carrying on the tradition of putting these things in cheerful surroundings.
The objective of the half-day session is to provide information on reactor technologies in order to allow the Panel to acquire an understanding of the reactors' principal design features, layouts, key operational parameters, overall normal operation, key safety systems, and the key similarities and differences of the technologies.
Three designs to be presented. We are glad they cut that down, instead of 5 or 10. Still, they will have to gloss over things to jam that much into a single session.

“Whether people are pro-nuclear or anti-nuclear, they don’t fault the process,” said Krizanc, adding the organization will need an overwhelming mandate from a community before it would be considered as a site.
I think they've added 'overwhelming' as something new. Probably like wanting the Olympics.

"Solidarity already warned in November this year that mining safety will have to be increased particularly in the silly season -- the last two months of the year in which there are traditionally more mining accidents."
'Tis the season for more rock bursts, la la lalalalalal......
I never knew that! The study of rock bursts in these mines formed the basis for my thoughts on all sorts of things. But this concept of more deaths being a 'silly season' is a bit weird.

How long must Canadians wait for Prime Minister Stephen Harper's government to settle on a remedy for the shortage of medical isotopes?
Hello? I just included this little tidbit to show the thinking processes of the bankrupt newspapers. :)
Harper is just as hopeless in this issue as all the other politicians have been. There aren't any brains left in all these institutions, since they completed their march to hard-core politicized self-similarity.
And could Keen have saved us all? Pulease! She was an uber-hack who drove out all the remaining brains in the regulator. I don't know why they have made her into a god.

A Korean consortium was picked to build Jordan's first small-scale nuclear research reactor, the Ministry of Education, Science and Technology said Friday.
"This is the most brilliant achievement so far in the 50-year history of the Korean nuclear industry. The deal will give us a chance to step up as a big-three producer of research reactors along with Argentina and Russia,"
We have obviously dropped out of the research reactor biz, what with all our failures, and bureaucratic entanglements. If we can't get India to build one for us, why not these guys? We should build it on solid, seismic-happy ground, like Port Hope! Then, our union people will be perfectly good to run the thing to the ground, and keep shoveling in fuel. The isotope business doctors will be happy, and all is good for Christmas! :)
Neat, it geolocates you and automatically gives a hazard of where you live. All these things should be taken with a grain of salt, since your exact foundation conditions skew things by an order of magnitude. But it's interesting.

Tungsten Wedding Rings
So, these guys ask me politely what it would take to put a link on my blog so they can plump up their Google ranking. Perfectly honest, and not like that link spam. I'm thinking, like a bottle of wine's worth of ad clicks or whatever, or I'm thinking - the nerve of these buggers, I am incorruptible!
But then, the concept of tungsten carbide wedding rings just rocked my whimsy! This stuff is for armor-piercing bullets! It will last forever! What if Tiger and super-model got this? They could build in a glass cutter, so she wouldn't have to smash the car window with a 9-iron!
So, I do this for free! Happy weddings to everyone!
Don't you just love those stock photos they always use on an earthquake story?
Seismologists believe that the buildup of stress deep in the earth causes earthquakes. Monitoring such stress has proven impossible to date.
Yeah! The above statement is the new 'global warming' of seismologists. Nobody can contradict this religion, or face exile and poverty. This, of course, means there are no earthquakes here in the east, because there hasn't been any localized build-up of stress in millions of years (or more).
The model does use simple physics, which is a great step up from just wiggle-line interpreting. It says you have to build up the stress, then BAM, then nothing until it starts all over again. Good for them! I'm not arguing. I'm hiding.....
I visit this old guy once a week, as part of my heroic volunteerism (Hi G!). He's 77, and can walk my legs off! I also got him into seeing my blog, and clicking on the ads (You better!). Cindy the Wonderdog comes and visits the whole household, including their murderous parrot.
So, one day we're walking on the river, and it starts to rain. In the wild areas, Cindy is a good dog off the leash (Don't tell that to the Dog Police!). So we duck under the Eglinton bridge, and it just starts to pour! There are these two nice chairs looking over the new graffiti, which is very nice, so the two old guys sit down and chat. I totally forget about the brown mutt! When the rain stops after a few minutes, I look around and she's gone. My heart sinks, and I'm ready for a tragedy, since she did something like this 5 years ago. So I go up to the road and whistle, and there she shows up! Seems a very nice couple had corralled her. They said she was playing in traffic! Whew!
Another day, we were walking again in the river valley, when we smelled something awful. G kept looking at his shoes, and I kept looking for overflowing sewers. It came and went. I began to suspect the dog, but she never came closer than 30 feet for some reason. I finally got her, and bent down for a sniff. GACK! CHOKE! WANNA BARF. OH GOD, I TOUCHED HER!
She had rolled in something long dead! Stay away from us, I told her, and we headed for the old ice rink. There was always snow that she could roll in. She went nuts in the snow, and that was enough to keep down the gag reflex. Finally, I had to put the stinker in the car, and give her a bath.
So, here's the title story. I've had 7 Mbits download from rotten Bell forever, but now I finally noticed that various servers were choking at that speed. Before, they could never get their overall throughput to match that. I don't have any choice here, since bankrupt Rogers has never upgraded our squirrel-infested lines, even though they say they did.
Naturally, I wanted to bump up the speed, since I have graduated to Youtube TV on the PS3, which is a great addictive time-waster. I would save the money by cutting off my Bell satellite, which had become horribly expensive ("Our new minimum plan, at a big hike, now comes with more channels!"). I phoned for the 16 Mb plan. -"Oh yes sir, you qualify, no problem!" After several days, nothing happened to my speed! I phoned technical support, and 7 Mb is the max my DSL line can handle! Mad I was! I got back to service, and asked for my old plan back. "Oh no sir, we don't offer that sweet plan anymore, it's 6 Mb for the same price, and we have to charge to bump up your download max".
Bugger! So today I checked, and the bleeps have choked the line to exactly 6 Mbits! And they are sending me a new modem because they were blaming that for the speed limit. Geez, the life of a monopoly. No wonder Canada is going downhill.
"We live in Hawaii and enjoy it, but we forget how special and unique it is," she said. "It is one of the most outstanding volcanic features on Earth, and scientists want to understand it."
This is much better than studying earthquakes in California! At least you can live away from the active volcano. Ah, what a job, beautiful Hawaii, a nice computer room with Sunacle computers. What could be better?
Everything now hangs on the success of the test welds, which are being applied near the corrosion spots on the huge, cylindrical vessel that contains the NRU's nuclear reactions and 65,000 litres of heavy water to cool and moderate the reactor. Nitric acid is blamed for the corrosion.
In a nutshell:
-35 year old aluminum vessel has been subjected to nitric acid - Can you say fizz?
-it's totally worm-holed and probably has a micro-structure of moldy bread
-in the world's worse seismic zone (due to Leda clay), and would do something dramatic in an earthquake
-they can't detect the 99% (almost through) wormholes
Now they are pasting over the known leaks with aluminum spray. The vessel is so hot it should just be hauled away and dumped in the back forty, like they've done with all their other rad-waste. Chalk River should be shut down. ... But that's just me talking.
The panel's report, released yesterday, urges Canada to keep pumping out its own isotopes, with a multipurpose reactor that could cost as much as $1.2-billion.
At last the silly news comes pouring in! I was dying. First of all, we have to get India to build it for us. Second, they would build it on the seismic death trap from hell - Chalk River. There would have to be a heck of a lot of 'global warming' corruption to get the seismic approvals for that swamp.

Nevada lawmakers said the analysis reinforces their contention that taxpayers are better off finding an alternative to the Yucca Mountain repository. Sens. Harry Reid and John Ensign requested the report, along with Sen. Barbara Boxer, D-Calif.
Yeah, the bean counters are magnificent!

He found through the isotopes preserved within the rocks that temperatures in the early ocean, at least in some spots on Earth, was about 40 degrees Celsius, which can be described as warm bath water. Previous to these findings researchers believed conditions were much hotter, around 70 degrees Celsius, 3.4 billion years ago.
This is too subtle for me! Hot is hot.

Holy Cow! I'm finally through the tons of video I shot on the weekend. This is the end of the Ontario varsity water polo season. Our girls (McMaster) won a tough bronze, which is great, considering they had almost all rookies this year.
Now I have to figure out how to down-scale this hd tv to dvd!
The Chalk River Employees Ad hoc Taskforce plans to launch a publicity blitz this week to try to rally support behind the beleaguered Chalk River NRU reactor, which employs close to 3,000 people and pumps hundreds of millions of dollars annually into the local economy.
I can't comment on this, since it sends water up my nose.
That tritium (Nuclear Waste!!) report was ridiculous, but we all know what happened to the CNSC over the years. As I have said, there is a consequence of having people think the CNSC is just a toadie clown car. It causes panics over stupid things, and interferes with a rational plan regarding nuclear energy.
Monday, November 30, 2009
So, I put up this piece of fluff, to say I've been at the Ontario University water polo tournament (finals) all weekend. That was exciting! As usual, my daughter was amazing! (biased opinion). I have so much video, and I'm slowly working through it.

The drink, named "Tactical Nuclear Penguin" is so strong that it should be served in small measures usually reserved for spirits.
Its maker, BrewDog brewers of Fraserburgh described the 32 per cent proof tipple as its "most audacious and ambitious project to date".
Gotta have something about Linux once in a while.

This just goes into the 'technical misc.' file, and I'm interested because I really want my very own Highlander, and the other half won't give me the money! :(
It is obvious that these thieves just went up to the cars and drove away. I'm also surprised that nobody had a lo-jack, since I always thought it was a matter of time before the car encryption is cracked.
You can click ads and help me save up. At the current rate, I will have enough in 150 years, give or take a century.

Now, I'm ready for the party season with all the university kids. Let's Part-eh!
Nobody has a clue what is going to happen there, but many try to step up to the plate. Most likely, it's the Cascadia subduction zone that will slip down in a manner identical to the big 2004 Sumatra M9. Even though it slips on a shallow-dipping fault that goes under the cities, the shaking will not be so big a deal. You would get a heck of a lot more from local M7's! What will be big is the tsunami and permanent elevation changes.
So, I think the main seismic hazard is from an urban M7, right under Seattle or Vancouver, or Portland. If you design for that, the 'Big One' is taken care of. (How long can you tread water? --Cosby).

Four students will be finally chosen from among the training camp participants, who will represent India at the fourth International Earth Science Olympiad (IESO) to be held at Yogyakarta, Indonesia from September 19 to September 28, 2010.
Olympiums drink an appropriate amount of beer and attempt to knock down a beer coaster house at 1m, by belching. No fair trying to use other orifices!
Geological Hammer Throw
Oympiadies throw a geologic hammer at an outcrop 30 m away. 1 point for hitting it, 1 point for hitting someone else, 2 points for getting the pointy end sticking in, and 3 points for pulling it out and discovering gold.
Hell, I can't think of any more. Help me out here!

As you can see, my favourite new site is TunnelTalk. It is the future of journalism. Conventional journalism is being flushed down the toilet. The media outlets are all closing, Kady O'Malley, who I just pant over, with her silver Blackberry fingers, (such a blur! swoon...), has been kicked out of bankrupt Rogers. Maybe CBC is the last bastion, but who knows how long that will last?
So, how will the middle son earn a living? The future will be micro-niche sites, that earn money from advertising. Really, where can Robbins spend their ad money anyway? TunnelTalk looks like it is run by two smart ladies that got kicked out of the local television news, which is dead. They own this niche!
This article looks at a big Albanian tunnel fiasco. To summarize: corrupt or incompetent government (who can tell which?) interferes directly with a technical project, and pushes it to be completed in a very short time. Not much investigative work is done, and rock is assumed to be good. In fact, it turns out to be very bad.
They find a willing contractor who hits the tunnel from 4 faces simultaneously. Temporary lining collapses, perhaps from an unseen borehole. They make it difficult for reporters to talk to them.
In this case, it would have been best to proceed with a pilot tunnel, to check the rock conditions, and perhaps do some grouting, or packing with sacrificial rockbolts.
A better, more realistic way to rescue the Canadian nuclear industry would be to sell AECL to India and use Indian technology for our next generation of Ontario reactors.
This is a good idea. We don't have the people anymore to do this, and when we did do it, we brought a heck of a lot of people from India! I think that only the Russians and the Indians can build a nuclear reactor these days.

Two American geologists have theorized that something happened to change the ecological balance, killing off the iron-loving bacteria and swinging conditions on the planet in favour of oxygen-producing microbes.I had read about this earlier, but this is a good article on the subject.
The world’s largest seismically isolated building, the new international terminal at Istanbul’s Sabiha Gökçen Airport, is now complete and open for business.
Stretching across more than 2 million square feet, the terminal doesn’t sit directly on the soil, but rather on more than 300 isolators, bearings that can move side-to-side during an earthquake. The whole building moves as a single unit, which prevents damage from uneven forces acting on the structure.
I haven't been a great fan of these things, but it looks like it could work here. I was more interested that they were using explicit finite elements (Dyna) to run the simulations. I love this stuff! I've done some of this code here, and I tried to push it at the old company. It's the only way to do earthquake analysis.
Now, if somebody would run these simulations for the whole shebang, from actual seismic generation, they would find it is better just having a good foundation, rather than using these base isolators. :)

"The crown fall happened in a area surrounding a 20-year old bore hole," said Ernst Gschnitzer, Project Manager for Strabag. "The hole had a long time to deteriorate and eventually the ground gave way."
I didn't exactly drill that borehole, but it was drilled shortly after I helped define the St. Davids Gorge with geophysics. That was just after the old Geotechnical Engineering Department broke up, and I was shuffled to nuclear. Before that, we always grouted up an exploration borehole, in fact it was the law because of possible natural gas in the region. My old colleagues have a lot to answer for!
So, the TunnelTalk article is out. I'm glad they could pin the 100 ton collapse to a single old borehole, because without that extraordinary cause, the whole tunnel would be suspect. The Queenston Shale is totally impermeable, so that was one heck of a hole to have caused water damage! I'm glad all the other holes didn't do this.
The sandstone has proven to be abrasive, and I think there are more sandstone layers ahead for them. I'm glad they talked to the reporter, since I wasn't expecting much. Oh well, it's good be wrong, since I was way too gloomy on this. If my mechanism is correct, we shall have some more major collapses, but for now, let's regard this happy article as a Christmas present! :)
Ontario Power Generation Inc. (OPG) reported a net income surge in the third quarter despite falling customer demand. Profit gains were mainly due to returns in investment branches set up to manage nuclear fixed asset removal and nuclear waste management, the company said.
But, they are going to blow it all on their Niagara Tunnel, and digging waste into Bruce karst.

Container cranes are used to load and unload ships in ports and are critical to port operations. Past earthquakes have highlighted the vulnerability of container cranes to damage from even moderate earthquakes.
I was about to give this my "Most Hopeless Research" award, but I've canceled that (it sounds nasty!). All research is interesting in some way. Still, you can see that the nature of the shipping crane makes it a 'disposable item' when an earthquake hits. The best you can do is have some other area ready, with cranes ready to erect. But the cranes aren't the problem here. Dock areas are almost always on dirt fill, put directly on muck. The seismic amplifications are 10 to 100 times, and not much survives. These shipping cranes are mobile on absolutely flat pavement, and that just isn't going to stay that way.
I think this project is more like designing earthquake-resistant shelves in a brick china shop. :)
Introductory geology courses at the University of Wisconsin Oshkosh and across the nation will teach rock-solid math skills to undergraduates studying the geosciences with the help of a new Web-based program.
“In the 1980s, we witnessed a decline in the amount of math included in introductory geology texts that coincided with an attempt to attract more students to the major,”....
Now, I know a lot of geologists, but they don't do math. :) They probably buy lottery tickets!
The preceding was a joke! I do not know of any Geologist Barbie Doll that said "Math is tough." Geologists are fine human beings.

A team of scientists led by the University of Adelaide has reconstructed a history of marine barriers, mountain building and glacial cycles in New Zealand over millions of years, using the first complete genetic history of the moa.
So, something interesting does happen in NZ! (besides geology scandals!) In a neat reversal of roles, you can get an idea of geology dynamics by looking at the dna of ancient species. Of course, our good neighbours down south, won't appreciate this.....
But the rest of us can enjoy the complexities of evolution.

I'm quite proud of these stills! I'm filming in hd video, but was zooming in real close to try to get stills. The video is terrible when you do this, but the stills are good. You then select frame by frame to get a good moment. Most is blurry because the shutter speed is slow, but some frames crystallize. I then use the 'unsharp' mask to eliminate the slight motion blur.
Far better than shooting stills in water polo, where the splashing water makes things difficult.

Work had been disrupted since Sept. 11 when there was a collapse of rock from a 25-metre section of the tunnel's ceiling. It occurred about two kilometres into the tunnel, more than three kilometres behind the spot where the tunnel-boring machine, nicknamed Big Becky, is cutting into the rock face.
This is all from a local news outlet, and is directly from the official mouthpiece. However, we learn that the collapse was much worse than I thought, with 25 m of lining taken out. That must be at least 500 tons of rock! I'd love to know how much extra overbreak there is now! And it's all been fixed with mesh and shotcrete.
We also learn that it completely blocked access to the TBM so I wonder how much 'scheduled maintenance' they got done. As well, we find out the Ministry of Silly Walks and Rock got involved, which is interesting.
So, do we think the tunnel is better off for having barfed up all this rock? Surely we must go with all those silly earthquake scientists who think that once rock fails, it will never fail again? (latest ENA earthquake theory). Sadly, the new configuration with the steep vertical arch is even more unstable under high horizontal compressive stresses. The rock failure will just want to work its way to the surface. And all the other rock will want to join in on the party!
After the rock failure in Scotland, and the recession, I can't believe these guys can get credit, investment, and insurance. Most amazing...
Where are those dang Tunnel News people anyway?
Over 41 years, the federal government detonated 921 nuclear warheads underground at the Nevada Test Site, 75 miles northeast of Las Vegas. Each explosion deposited a toxic load of radioactivity into the ground and, in some cases, directly into aquifers.
Good old Reid-country is on a new kick to suck money from Obama. This water moves so slowly that it will take 6000 years to reach the nearest pitiful community (I'm sure the dust got there a lot sooner!). Nevertheless, Nevada wants compensation for all that water!
Forget the fact that they sucked all the money out of California with their gambling, they want more!

The £150million Glendoe scheme ground to a halt just two months after it opened following rock falls within its massive water tunnel.
Thanks to Hypocentre who pointed this out to me. We've already had our rockfall in the Niagara Tunnel, even before it's built! I wonder if it was the same contractor? Can't be too many of those around the world....
Oh, pooey, it's some other Austrian-sounding company - Hochtief. It was 20,000 tons of rock, and they used an unlined TBM tunnel.
Maybe they're Austrian cousins?
Investigations of the exact quality and condition of the rock at the location of the rock failure and the exact causes of this embarrassing, costly and serious situation for a brand new hydroelectric power station project continue.
This is scandal is really perking me up! From unknown sources, we have this map of recent epicentres around that canal I wrote about.
Under intense pressure from the utility, the little newspaper buggers have completely zapped the article, but I hope somebody can find it. Basically, this canal area has been riddled by earthquakes, with many new fault traces showing up all over the place. Suddenly, without word to any of the local workers, they decide to drain the canals. Que passa? These poor guys are caught trying to save the fish with their bare hands! A decent human being would have pre-netted before draining.
Ah, local geologist, who is very nice, deserves a high paying job, yada yada, is suddenly badly misquoted, and soundbited to death by the local media. Her point was that these things don't suddenly happen, and there must be a reason. Most likely, the canal has been split by earthquake faulting.
"Ah no! She is crazy!" cries the mouthpiece of the utility. "We don't even know what earthquakes are, so how can it be an earthquake?" Poor lady is mucked by having a mud wrestle with porcine people.
So, although they are attempting to squash all this, the internet is harsh. As a geotechnical engineer with many years of experience with these stupid canals and water tunnels, my scenario is this: They suddenly found themselves with less water at the gate than expected. The canal is on porous volcanic shit, and uses a fairly thin clay lining, under some sort of erosion rip-rap. It is very easy to rupture, and when it does, a lot of water leaks out, which is instantly shown at the gate. You drain the canal, but it is very nasty to find this sort of thing. I would suggest an electromagnetic survey, to try to find soggy bits.
Now, of course I could be all wrong, but when utilities play this game, I rise to the challenge, and make up the nastiest explanations.... :)
But, Scharnberger added, the fact remains that there’s a lot that isn’t known about this series of small earthquakes, of which 817 have been reported to date, several of a magnitude about 2.9 but most registering at less than 1 on the Richter scale.
SAN FRANCISCO — The Bay Bridge fix that halted traffic across the span for more than five days was not inspected by federal authorities, The Examiner learned, despite public promises from the state agency that oversees the structure.
No comment, I'm going down again.

Geologist Donna Falconer claims Meridian's explanation doesn't stack up and believes they are looking for damage in the canals.
"You only have to drive along the canals and see all the heavy earthmoving gear ... They are looking for leaks down in the zone where all this seismic activity has been."
I'll have to go with Crazy Donna* here! What are they doing with this? Most likely they have a significant increase in water leakage, as measured at the gate. So, you've got to drain it and look, in the middle of night, when nobody sees you! Ha, Ha!
*term of endearment.
The NRC has asked Westinghouse to revise the design of the AP1000's shield building, which is the outermost structure of the reactor. Regulators said it was unclear whether the shield building, as designed, would be able to withstand earthquakes, tornados or other disasters.
Yeah! Earthquakes are back to totally muck up the plans of mice and men!

With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience.
These sections are always fascinating. What makes a fault section less 'crunchy', and more of a slow grind. It could be rock type, but I think it has something to do with water. At this section the rock does not have a large difference between static and dynamic friction. It is the equivalent of grinding two bone-dry bricks against each other. However, I can't believe that water is totally out of the picture here, so I think this section will surprise us one day.
The goal of a great career, the goal of really powerful people, is to work as intensely as they can for the shortest amount of time possible. That's what you want to do.
This is my book! But, it's too much work putting out a book, so I don't think this guy is a real slacker, he just pretends to be. I always found that people who worked every second were pretty dumb. I always found ways to do a tenth the work, and then just flow like I was everyone else!
And at the end, I felt I earned more than Bill Gates, normalized by income per time worked!
The city was built on a material known as Belfast sleech — a complex mixture of sand, gravel and boulder clay that has caused serious headaches for the team building the Belfast Sewer Project.
Now, that's some serious tunnel work! Only one minor collapse, and they haven't yet stopped to demand more money!

"You start with the world where you and I are getting an exposure from the sun, from the soil we walk on, from the brick in our house that on average is about 400 millirems a year -- which is dangerous," said Tom Lenhart, a former member of the federal-state Interagency Steering Committee on Radiation Standards. "The EPA would never allow that kind of exposure. So you are starting from a baseline of dangerous exposure, and this is what makes regulating it a nightmare."
We can't live.....
Seriously, if you cut down the standards to ridiculously low levels, you can't do anything. I mean, you can't dig this stuff and dump it somewhere! Of course, the natural gas would displace coal, which throws out more radiation than Port Hope!
The boreholes at Campi Flegrei won’t likely hit magma, researchers say, as the holes will reach only half as deep as any known reservoir, and even if it does, the result will not necessarily be a disaster. It could, rather, provide researchers with important new information about the inner-workings of volcanoes in general, and Campi Flegrei in particular. Meanwhile, Naples will simply have to hold its breath.
Dum, dee, dum, I'm drilling into a volcano....
That warm brew is laden with minerals. And its source is generally thought to be “meteorological”—that is, rainwater that soaks deep into the Earth, where it’s heated by geothermal forces.
But new research at James Madison University’s Department of Geology offers an additional explanation.
Last fall, associate professor Steve Baedke and then-undergraduate Nick Silvis took several samples of the thermal waters of the geological region known as Warm Springs Valley.
Tests by Lawrence Berkeley National Laboratory in California showed traces of a rare helium isotope—a signature of water not from the top layer of the Earth, the crust, but from the middle layer, the mantle.
I've always wondered how you can get a hot spring in the middle of very stable crust. How the heck is it possible? Now it appears that there is a really deep connection. If this water comes up, then replacement water has to go down, in a huge flow system. I find it quite amazing.

Luckily, I'm the master of the 120 Sleep! I'm zooming along the 401 in an empty zone, and I can click my eyeballs to lock, and go to a Selective Temporary Lobotomy (STL). Then, an hour later, I suddenly wonder where I am! I'd love to see this on a PET scan! I think it must be some ancient evolutionary advantage:
The mighty hunter, sitting on a ledge, waiting for the prey. ZAP! STL to conserve energy. Something wanders in to his field of view, lets go the spear, and hopes it's edible!
2 million years ago, the great Division of Labour between the sexes. The man invents power tools, so he can get alone more. The woman talks, and ZAP STL! Those men unsuccessful at it do not become successful breeders.
Modern times, any woman talking to you, STL! You must still be totally alert for sharp objects, or 'attention checkers', such as "I'm going to sign us up for dance lessons."

If it is the transformer, we can expect it to be down for several months, provided they have a spare, ready to go. If it turns on tomorrow, forget I said anything. :)

On November 1st 2009
Scheduled maintenance of TBM is in progress
The Invert Concrete Bridge is 2,640 meters (8,661 feet)
On September 11th 2009
The tunnel is 5418 meters (17,775 feet) long
Over-break is 3.5 meters (9.8 feet)
average 5-7 meters per day
elevation below surface 89 meters (294.5 feet)
mining halted following a fall of ground at 3,600 meters
pending debris clearing and repairs to the effected area
as well as a scheduled six week shut down for maintenance of the TBM
mining has been delayed
Sorry everybody. I had assumed the reason we weren't hearing anything was the result of some evil squelching of the news. But, brand new on the site, they are telling us that everything has stopped for maintenance. Whew!
