M8.0 Alaska earthquake - standard subduction


Right at the tail of Alaska.  This was registered as deep, and quite inward.  Little chance of a tsunami, but they pulled the big horn anyway.



This is a very clean but highly curved subduction zone.  An 8 is small beer to the giant scratch on the Earth, and it must pull regular M9+'s to keep its clean lines.  When we see such an earthquake, then it is time to clear the beach.  I'm going to Maui soon, and I will not let go of my shoes!

Update:  This is when it hit Ontario.  Most of the other plots are solid black.  I really think this will rattle up some OK earthquakes.

There was a kind of microtsunami recorded at Maui: http://www.ioc-sealevelmonitoring.org/station.php?code=kahu2

The disturbances are more clear at these AK stations:
