Magnitude 4.1 earthquake strikes southern Ontario, Canada

A magnitude 4.1 earthquake has struck southern Ontario, Canada, according to the United States Geological Survey (USGS). Shaking was felt across parts of Ontario and reported as far south as Rochester, New York.

The quake struck at 10:59 p.m. local time at a shallow depth of about 11.5 kilometers (7 miles), according to the USGS.

The epicenter was located near the town of Brechin, close to Lake Simcoe, about 45 kilometers (28 miles) east of Barrie and roughly 104 kilometers (65 miles) northeast of Toronto.

People across the region reported feeling the shaking. One social media user in Toronto said their “whole house shook for about six to ten seconds.”

Additional reports of shaking came from Oshawa, Millbrook, and Lindsay in Ontario, as well as from parts of New York state, including Rochester.

Earthquakes are relatively uncommon in Ontario, but the region does experience occasional seismic activity, particularly in areas near ancient fault lines in eastern and central Canada. Most earthquakes in the province are small and rarely cause damage.
