Hidden earthquakes reveal 'Doomsday Glacier' threat; major US cities, 12M people in danger

Key Points:
- Scientists have discovered over 360 previously undetected earthquakes beneath Antarctica’s Thwaites Glacier from 2010 to 2023, revealing new details about the glacier’s instability.
- The earthquakes, producing low-frequency vibrations missed by standard methods, mostly occurred near the glacier’s edge with the Amundsen Sea, where large icebergs frequently calve.
- Thwaites Glacier, known as the “Doomsday Glacier,” could cause global sea levels to rise by up to 10 feet if it collapses, threatening millions of people and major U.S. coastal cities like New York and Miami.
- The seismic activity is linked to mechanical ice failures and melting at the glacier’s base due to warm ocean water, contributing to
