Antarctica Doomsday Glacier Rattled by Hundreds of Iceberg Earthquakes

Scientists discovered over 360 glacial earthquakes in Antarctica between 2010 and 2023, with most occurring near the Thwaites "Doomsday" Glacier that could raise sea levels by 3 meters if it collapses. These earthquakes happen when massive icebergs break off and capsize, crashing into the glacier and creating seismic waves detectable across thousands of kilometers. The peak activity between 2018-2020 coincided with accelerated ice flow toward the ocean, suggesting ocean conditions may be destabilizing this critical glacier faster than previously understood.
