Summary of Southern Ontario Earthquakes

I throw this up every year or so.  You'll notice the influence of the two megathrusts under Lake Ontario.  The gap between Hamilton and Cleveland is due to a huge Precambrian basin, shown in the reflection seismic.  The Hamilton fault is strongly defined.  These earthquakes continue to show a strong affinity to water, and are generally at a fraction of the rate of Oklahoma.  The rare earthquake (1 in 500) is a 6+.  The 'destructo' is an M7.  This class of earthquake is strongly shown in the sediments.
