Earthquake in northeastern Ohio felt in Canada

On New Year’s eve, a magnitude 4.0 earthquake occurred in northeastern Ohio and was felt by many Canadians just the other side of the border, as well as by people throughout Ohio and Pennsylvania. As earthquakes can affect countries which share borders, such countries generally share seismic data between their earthquake research institutions. This is the case for the Geological Survey of Canada and the United States Geological Survey, which benefit from this type of collaboration frequently.
