Has Anyone Heard a ‘Frost Quake’ During This Tri-State Deep-Freeze? [VIDEO]
The daughter of a friend of mine lives in Chicago and she was wondering if we had experienced a 'frost quake.'
Since I have no idea what that is...couldn't tell ya.
So I looked it up.
WLFI/West Lafayette, Indiana meteorologist Balint Szalavari explains that a cryoseism, or frost quake, happens "when extremely cold temperatures lead to rapid freezing in the ground after it has been saturated."
This, in turn, creates a booming noise when the ice expands in the ground.
It seems they're more commonly heard at night, when there's less noise with which they can compete.
Here's a demonstration:
And here's an actual frost quake:
I think this is really cool, but it IS helpful to know they exist so, if you hear one, you don't jump out of your skin.
Happy frost quake hunting!
