More popularly known as ice quakes or frost quakes, because they feel and sound like minor earthquakes, cryoseism is most common on glaciers, where ice is continually expanding and contracting, leading to great booming cracks as fissures form in the ice.

What causes an ice quake?

– When water deep in the earth’s crust freezes and expands, nearby ground and rock can crack, causing a “frost quake.” … A quick freeze, such as when temperatures rapidly drop within a day or two, also make frost quakes occur. Unlike other seismic events, vibrations caused by frost quakes are not felt above ground.

What is the difference between ice quakes and earthquakes?

Meteorologists weighed in with their own explanation: Frost quakes. … But unlike earthquakes—which occur when the slow-moving plates of the Earth’s crust suddenly slip—cryoseisms are caused by sudden cracks in frozen soil or underground water, and are weather-driven, not tectonic.
