Residents from Cleveland to Columbus may soon hear strange booms or experience small earth tremors as temperatures drop. According to the Ohio Department of Natural Resources (ODNR), these strange sounds are most likely frost quakes, an uncommon winter phenomenon that occurs when moist earth freezes too rapidly.
Frost quakes, also known as cryoseisms, occur when rain or melting snow seeps into the earth and freezes quickly as temperatures dip below zero. The expanding ice builds up pressure underground until it cracks, resulting in a loud, explosive sound and, sometimes, a tiny ground vibration.

Meteorologists say circumstances in northern and central Ohio are ideal for frost quakes this week, thanks to two rain systems followed by frigid air. The greatest risk arises when snow cover is thin or absent, allowing cold air to penetrate deeply and freeze contained rainwater.
These episodes usually happen overnight, between midnight and morning, when temperatures are at their coldest. Frost quakes are rarely destructive, although they can produce minor cracks in roads or foundations and are sometimes mistaken for distant explosions or small earthquakes.
Experts advise fixing drainage around homes and ensuring gutters and downspouts divert water away from structures before strong freezes.
So, if a huge explosion wakes you up on a peaceful, icy night from Cleveland to Columbus, don’t be alarmed; it’s simply the frozen Ohio ground snapping under winter’s pressure.
