Frost quakes are non-tectonic seismic events, meaning they are not caused by the shifting of the Earth’s tectonic plates. My Forbes colleague Robin Andrews wrote about frost quakes recently, but I wanted to dive more into … The size of these crystals depend on time, temperature and the humidity of the air. frost quakes explained "Cryoseism is a special form of seismic event (ie: earthquake), not caused by moving tectonic plates, but instead, it is a result of the sudden onset of extreme cold," explains Weather Network meteorologist Scott Sutherland.
