Frostquakes, also known as ice quakes or cryoisms are seismic events caused by a sudden fracturing or cracking action in frozen ground soil or rock. Frostquakes have been reported in recent years in Connecticut, Massachusetts, Maine, Vermont, Michigan, Wisconsin, Ohio, Indiana and Missouri. It's one of the most powerful fault lines in the whole world. We're a fault line. New madre fault. Must say that what was the last one? I think I remember like, 1906, it was in the 2007. The earthquake actually rang church bells all the way from Missouri and Boston.
