Cold weather can sometimes trigger loud booms known as frost quakes. Meteorologist Ricky Matthews explained on Facebook that these happen when the ground freezes rapidly and cracks under pressure, most often after winter weather events.
Rain or melting snow seeps into the soil and rock cracks beneath the surface. If temperatures drop suddenly, that trapped moisture freezes and expands quickly. The expanding ice creates intense pressure until the ground snaps, producing a loud noise and brief shaking.
Although they can feel like a small earthquake, frost quakes are caused by weather, not shifting tectonic plates. Common signs include:
- Sudden booms: Sharp cracking or popping sounds
- Quick jolts: A short, localized vibration
- Short duration: Shaking that lasts only a few seconds
Frost quakes are harmless but can be startling, especially during extreme cold snaps.
