What are frost quakes?
According to the Maine Geological Survey, a cryoseism, or what is commonly referred to as a frost quake, is a phenomenon that produces ground shaking and noises similar to an earthquake but is extremely localized. Frost quakes typically occur in areas where moisture in the ground freezes and expands rapidly. These events are commonly reported in Canada, Northern Europe, Russia, around the Great Lakes and along the U.S.-Canadian border.
