A moderate earthquake hit eastern Canada on Friday morning.
It happened at about 9:43 a.m. in Southern Ontario and was preliminarily measured as a magnitude 5.1 by Earthquakes Canada.
There were many reports of shaking in Ottawa, Toronto, Montreal and locations in northern and western New York and northern Vermont after the quake. There were even reports in northeastern Pennsylvania. There were no immediate reports of injury or damage.
Twitter erupted with reports of buildings shaking in Ottawa for several seconds. Ontario's premier, who lives in Toronto, tweeted that her house was shaking, according to the Associated Press.
New York Gov. Andrew Cuomo issued a statement saying that no reports of damage to the state's infrastructure have surfaced.
"The State Office of Emergency Management continues to monitor effects of the earthquake that occurred this morning near Ottawa, Canada, and was felt throughout parts of New York State," Cuomo said.
According to the United States Geological Survey (USGS), the two largest damaging earthquakes in the Western Quebec seismic zone occurred in 1935 (magnitude 6.1) at the northwestern end of the seismic zone, and in 1732 (magnitude 6.2) 450 km (280 mi) away at the southeastern end of the zone where it caused significant damage in Montreal. Earthquakes cause damage in the zone about once a decade. Smaller earthquakes are felt three or four times a year.
Earthquakes east of the Rocky Mountains, although less frequent than in the west, are typically felt over a much broader region.
