Over 360 iceberg quakes detected near Antarctica’s Thwaites Glacier, signaling rapid ice loss linked to climate change.
A new study using local seismic stations has detected over 360 iceberg-related quakes near Antarctica’s Thwaites and Pine Island glaciers, primarily near Thwaites—known as the "Doomsday Glacier."
These glacial earthquakes, caused by massive icebergs breaking off and capsizing, were previously undetected by global networks due to their low-frequency signals.
Peak activity from 2018 to 2020 coincided with accelerated ice flow, likely linked to changing ocean conditions.
A second, unexplained cluster near Pine Island Glacier highlights gaps in understanding.
The findings underscore the need for localized monitoring to track climate-driven glacier changes and sea-level rise risks.
