Loud Mystery "Booms" Last Night During Arctic Cold? Here's What It Was!

If you heard loud booms overnight and this morning, you weren't alone.

KWQC Meteorologist Kevin Phelps explains that what we heard in the QCA were "Frost Quakes". Technically, the term for the sounds are "Cryoseisms". ( Link to his quick video )

The sound happens when water in the ground freezes too fast instead of gradually (like a soda pop can in the freezer!) which causes soil and rocks to crack and go "BOOM!" (See picture below...)
