icequake
Frozen ground shaking
An icequake is a seismic event caused by sudden cracking or movement within a glacier, ice sheet, or frozen ground.
Like earthquakes, icequakes release built-up stress, but in ice rather than rock.
They range from small pops to significant tremors that can be felt or detected by instruments.
Climate scientists monitor icequakes to track glacial activity and ice sheet stability.
