Sitting in front of my computer at about 1:45pm today, the walls started to sway and creak and the venetian blinds started flapping, only a few seconds and it was over, with more creaks and groans from the walls of the 110 year old house a few minutes later. People out in the street didn't seem to notice and just carried on with what they were doing.
But OlderSon felt it too, about 4okm away. Weird feeling! Made me want to run outside. But earthquakes just don't happen here in S Ontario.... or do they????
The Globe and Mail says it was 5.0 on the Richter scale. Here.
