You’re not alone if you’ve heard mysterious loud booms in the MidSouth this week.
The National Weather Service explains, this is a weather-phenomenon called a Cryoseismic Boom. The boom is also more commonly known as an ice quake. Ice quakes happens when frozen water expands quickly in the ground. When water runs into the ground and the temperatures drop dramatically, the water in the ground freezes and expands, putting stress on the ground. That stress builds, which is when you hear a loud boom.
All of the snow and ice Middle Tennessee & the Mid-South has seen the past couple of days, melts during the day and creates the perfect scenario for ice quakes to happen.
