Extreme cold causes 'frost quakes'

Posted:

MARKESAN (WKOW) -- The extreme cold this week has chilled many of us to the core.

And it's working its way deep into the ground, too.

So deep, that it appears to be causing what scientists refer to as frost or ice quakes; seismic activity similar to an earthquake, caused by water freezing deeper than normal.

Not only does the ground move, it's noisy, too.

Residents of Fond du Lac and Green Lake counties experienced an apparent ice quake Monday night.

There were numerous witness accounts of shaking and booming felt and heard from Markesan to Princeton to Friesland.

Other than frayed nerves, no damage was reported.
