How many hidden earthquakes were just found under Antarctica's Doomsday Glacier?Scientists detected hundreds of previously missed seismic events beneath the region, including 245 near the marine edge of Thwaites Glacier, offering a new way to monitor ice destabilization.What happened: In a recent analysis of seismic data, researchers identified over 600 hidden earthquakes under Antarctica, with 245 occurring near Thwaites Glacier's marine edge—many triggered by glacial ice fracturing rather than tectonic activity. The study, released in November 2025, reveals that these so-called "glacial earthquakes" happen far more often than previously thought, especially as warm ocean water weakens the glacier from below.Key numbers: 245 quakes located near Thwaites Glacier's marine edge600+ total hidden seismic events found across AntarcticaThwaites Glacier could raise sea levels by over 2 feet if it fully collapsesWhy it matters: These tiny quakes act like early warning signals—hearing them lets scientists track how fast the glacier is fracturing, which is critical for predicting sea level rise.Bottom line: The Doomsday Glacier's heartbeat is louder than we thought, and it's whispering secrets we can finally understand.
