Scientists have recorded hundreds of earthquakes over more than a decade, caused by the calving and capsizing of icebergs near the Thwaites Glacier off the coast of Antarctica. These icequakes occur when massive icebergs break off from the edge of an ice sheet, fall into the ocean, and capsize, forcefully striking the continental ice and generating seismic waves capable of traveling long distances. Seismologists have revealed evidence of over 360 icequakes in Antarctica between 2010 and 2023, with the majority—245 of them—concentrated near the marine edge of the Thwaites Glacier, known as the "Doomsday Glacier." These tremors...
