A 5.0-magnitude earthquake hit Quebec today, with tremors felt throughout southern Ontario and the northeastern United States and was likely caused by a geological phenomenon called “isostatic rebound,” said University of Toronto geologist Russell Pysklywec.
The first tremor hit at 1:41 p.m. ET south of Echo Lake, Que., 61 kilometres north of Ottawa near the Ontario-Quebec border. In a release, the City of Toronto said its officials are looking for signs of quake damage. “In our initial assessment, there has been no major damage to City infrastructure,” it said in the release. “The City has received no calls concerning bridge, building or other infrastructure problems.”
