"Glacial earthquakes are a special type of earthquake generated in cold, icy
regions. First discovered in the northern hemisphere more than 20 years ago,
these quakes occur when huge chunks of ice fall from glaciers into the sea.

Until now, only a very few have been found in the Antarctic. In a new study
soon to be published in Geophysical Research Letters, I present evidence for
hundreds of these quakes in Antarctica between 2010 and 2023, mostly at the
ocean end of the Thwaites Glacier – the so-called Doomsday Glacier that could
send sea levels rising rapidly if it were to collapse."
