(Fort Wayne’s NBC) – Have you heard loud “booming” noises lately?

It could be an ice quake or frost quake, which scientists call a cryoseism.

The National Weather Service in Lincoln, Illinois says they’ve confirmed reports of loud booms and shaking ground in central Illinois.

They say the frost quakes are coming from the rapidly dropping temperatures.

This phenomenon can happen when moisture in the soil rapidly freezes.

As the water freezes, it expands and puts pressure on the surrounding surfaces.

The pressure has to be relieved, so that’s what causes the loud, harmless booms.
