Bizarre earthquake felt in Toronto
M2.5. I am calling this bizarre, since we get this size of earthquake all the time around here. So, why did I see it on the wall tv, while I was eating my fish and chips in Hamilton? It's because this seemed to put a hefty PGV (peak ground velocity) for its magnitude. Perhaps we should call it a Canadian M3. :)
I like this location because it was at one of my obsessions early in my career - the Clarendon-Lindon fault system. This was treated as something grand for a long time, until we found out it was the surface disturbance of a deeper Precambrian megathrust. But, at the time, it was a star, and the whole Darlington seismic design was hinged on it.
Anyway, as usual, if you felt this earthquake in Toronto, you are in real doo-doo should we have a 'real' earthquake, because your soil is amplifying by more than 10 times. Have fun!
