Hundreds of earthquakes have been detected rattling Antarctica’s Thwaites Glacier, also known as the Doomsday Glacier — the disintegration of which could send between two and 10 feet of devastating flooding to coastal communities worldwide. Glacier earthquakes are detected at around magnitude 5 on the Richter scale, and are often associated with iceberg calving in warmer months of the Arctic Circle such as the ones in Greenland. By contrast, the dynamics that drive Antarctic earthquakes are little understood because there is simply isn’t much data on them and they tend to register at a lower magnitude. From this data, he determined that 245 of the 362 earthquakes recorded came from Thwaites Glacier, where he believes they were caused by icebergs calving off into the ocean.
