Came across this interesting tidbit over at AccuWeather.....
(AccuWeather) 'Frost quakes' could shake areas experiencing extreme cold
If you hear a loud boom and feel the ground shake during an extreme cold event, it likely wasn’t an earthquake. A cryoseism, also called an ice quake or a frost quake, occurs when water that trickled down into the ground during winter freezes and expands.This puts stress on the surrounding earth and reacts much like how an earthquake occurs as tectonic plates buckle or bend. These frost quakes can happen almost anywhere that experiences extremely cold weather, such as the Northeast, the Great Lakes region and Alaska.
