SUNY Potsdam professor emeritus Frank Revetta said the earthquake felt by many North Country residents today may have done some damage in Canada.

“Earthquakes are common in this region, but they are usually twos or threes, this was a size five and that’s a damaging quake,” he said.

Residents reported feeling the earthquake this morning in both Potsdam and Canton.

Rebecca J. Faber, spokesperson for Canton-Potsdam Hospital, reported to staff that the quake had occurred at 9:43 a.m. and said that "there is no indication that damage may have occurred to any of our facilities."

"At this time, there have been no reports of damage to any of the state’s critical infrastructure,” a statement from Gov. Andrew Cuomo said.

The USGS data say that a temblor with a Richter scale reading of 5.0 shook the ground in Quebec and surrounding areas at 9:43 a.m.

The epicenter, or the spot on the earth's surface directly above the sub-surface event, was 25 miles north-northeast of Shawville, Quebec, or about 100 miles northwest of Massena.

The quake was 5 kilometers below the surface, not particularly deep for an earthquake, according to the USGS.
