TOLEDO (WTOL) - We’ve all heard of an earthquake, but have you ever heard of a frost quake?
Or a better question might be, have you ever heard a frost quake?
A cryoseism, the official term for frost quake, is what’s going on when you hear a loud crack or boom on a cold winter’s night.
So why does this happen?
According to the Smithsonian, this happens when rain and ice seep down into the soil, then freezes and expands. When the frozen water expands in the ground, it releases energy and shifts the ground, much like an earthquake does.
Some people in our area heard them last night! Meteorologist Ryan Wichman says they are more common where the ground is not covered with so much snow.
Did you hear one last night?
