FROST QUAKE: A cryoseism, ice quake, is a seismic event caused by a sudden cracking action in frozen soil or rock saturated with water or ice, or by stresses generated at frozen lakes. As water drains into the ground, it may eventually freeze and expand under colder temperatures, putting stress on its surroundings. The sudden expansion and movement can result in the ground becoming cracked. You may hear a loud noise or feel the ground shake briefly.

The requirements for an ice quake to occur are numerous; therefore, accurate predictions are not entirely possible and they are rare in general.
