SOUND UP … This is video coming from Munfordville, KY of the frost quakes occurring today. The loud bang is caused by water expanding and freezing in the ground of these extreme temperatures. The frost quakes normally have a loud boom and can have shaking with them. 🎥 sent to me by Angie Puckett. | Marc Weinberg

FROST QUAKES - You might have heard these sounds recently? 🎞 Anthony Bond - This happens when water freezes and expands inside a crack, acting as a wedge along any particular fault (dirt, masonry, stone, etc.) When that wedge expands just enough it force the crack to suddenly break wider. It can be a pop, or it can shake the house. Often sounds like someone fell out of bed or a car-crash in the neighborhood. | Brandon Butcher
