Antarctica’s Hidden Icequakes Reveal Ocean Impact | Science News

Hundreds of hidden seismic events beneath Antarctica have been uncovered—245 near the ominous Thwaites Glacier, dubbed the “Doomsday Glacier.” These aren’t regular quakes but glacial earthquakes triggered when massive icebergs break off, flip, and slam into the glacier, sending shockwaves across thousands of kilometers. First spotted in Greenland two decades ago, these rare tremors were previously undetectable in Antarctica due to their low-frequency nature and lack of sensitive local monitoring. A new study reveals over 360 such events between 2010 and 2023, mostly near Thwaites and Pine Island glaciers, coinciding with accelerated ice flow toward the ocean—a troubling sign that warming seas may be destabilizing these ice giants and accelerating sea-level rise.
