We just had an earthquake. I'm quite sure of it. Anyone else? Where was the epicentre?
Update: Yes, indeed. Epicentre 45 km NE of Ottawa, 4.0 on the Richter scale, according to the Edinburgh Earth Observatory, and 4.5 according to the Geological Survey of Canada here in Ottawa.
(A three-times-a-day event for you Californians, I know, but a little more noteworthy in these parts.)
