Hundreds of hidden earthquakes found at Antarctica’s Doomsday Glacier
Researchers found 362 glacial quakes in Antarctica, and 245 were near Thwaites Glacier, a cluster linked to capsizing icebergs.

Hundreds of hidden earthquakes found at Antarctica’s Doomsday Glacier
Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be glacial earthquakes caused when huge icebergs break off, capsize, and collide with the glacier. The surge in activity coincided with a period when Thwaites was flowing faster toward the ocean, hinting that changing ocean conditions may be destabilizing the ice.
Researchers have detected hundreds of glacial earthquakes in Antarctica, especially near the Thwaites Glacier, known as the "Doomsday Glacier." The seismic activity, which occurred between 2010 and 2023, raises concerns about the impact of melting ice on global sea levels. Detection of glacial earthquakes in Antarctica The research revealed the occurrence of 360 seismic events, most of which were not recorded in earthquake catalogs. These events…
