A regional seismic search found hundreds of overlooked signals around West Antarctica, but the Thwaites interpretation rests on converging evidence rather than 245 satellite-confirmed capsizes.
Researchers detected 245 largely uncatalogued seismic events near the ocean edge of Antarctica’s Thwaites Glacier, most likely glacial earthquakes caused by capsizing icebergs—and the busiest period coincided with episodic acceleration of the glacier’s floating ice tongue toward the sea.
