Ontario-Quebec M4 earthquake

This doesn't rate much attention, but look at the big difference between an M4, M5, and M6, all of which we've had recently.  When I look at a new earthquake that's come down on the wire, such as the India earthquake, I look to see if there's any population, and then I decide whether it's an 'every day' event or not.  A series of common earthquakes has already knocked down everything there is to tipple over.
