Hundreds of previously overlooked seismic events have been detected beneath Antarctica, many apparently glacial earthquakes caused when huge icebergs break off, capsize, and collide with the Thwaites glacier. The activity surge coincided with a period when Thwaites was flowing faster toward the ocean, indicating changing ocean conditions may be destabilizing the ice. A collapse could send sea level rising rapidly.
