Collingwood Earthquake

Article


This was in the news. As we can see there are a lot of earthquakes around there. Who cares?  Obviously the deep waste thing doesn't.  As we can see in the other lakes, our earthquakes follow both the water and the Precambrian structure. Thus the earthquakes in Georgian bay are in the hanging wall of the Grenville Front. This is an unstable area and cannot tolerate either injection or extraction.
