What’s that boom? Cold winter temperatures cause ice quakes
MADISON, Wis. — On a calm, cold winter night, a sudden explosive sound may be enough to make you jump out of bed.
Did you hear a loud ‘boom’ today?! We’re actually getting several reports around the area… and there’s nothing to fear! Those pops and booms are called ice quakes; they’re caused by the water in the ground freezing & expanding #News3Now pic.twitter.com/0TKWFPe31J

There’s no need to be alarmed; the boom was likely an ice quake.
Ice quakes, also called frost quakes, happen when water in the ground freezes and expands. The expansion can create very loud, frequent pops.
