Loud booms reported across the state are the result of cryoseisms, or “ice quakes.” The phenomenon occurred when the ground rapidly freezes and cracks develop in the ground, leading to an explosive sound.

Did you hear a big boom sometime overnight? You’re not alone.

Chief Meteorologist Ryan Hanrahan said those loud noises, which have been reported across the state, are the result of cryoseisms, or "ice" or "frost quakes.” The phenomenon occurs when the ground rapidly freezes and cracks develop in the ground, leading to an explosive sound.

According to the Maine Department of Agriculture, Conversation and Forestry, these quakes happen in upstate New York, Vermont, Massachusetts, Connecticut and Maine.

A blast of cold air hit after the storm Sunday, and temperatures are hovering near zero across much of the state. For more on the cold, click here.
