AMAZING WEATHER FACT - The 1663 Charlevoix earthquake was a major earthquake that struck the entire eastern part of North America at 5:30 p.m. on February 5, 1663. The main shock epicenter is suggested to have occurred in the Saint Lawrence River and along the Saint-Maurice River. Great landslides along the Saint Lawrence, Saint-Maurice, and Batiscan Rivers made these rivers muddy after the shock. The earthquake was felt sharply in New England. On the shores of Massachusetts Bay, the tops of chimneys were broken on houses and pewter was jarred from shelves.
