Calgary, a prairie city far from any nearby fault lines, felt an unfamiliar sensation early Tuesday evening — an earthquake. A 6.5 magnitude quake occurred at a depth of 10 kilometres near Challis, Idaho, at 5:52 p.m. MT, and was felt in Calgary just a few minutes later. #yyc #earthquake #calgary —@rikkiprinceMy mom just called from work (Foothills Hospital) claiming they just felt the building move like an earthquake. John Cassidy, a seismologist with Natural Resources Canada, said the earthquake was a large one, and was felt in southern B.C., Montana and Utah as well. The last time Calgarians felt a large earthquake was in 2017, when a 5.8-magnitude quake shook Montana.
