Doomsday Glacier

Seismic Activity Intensifies Under Thwaites Glacier, Revealing Ice Dynamics

Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near Thwaites Glacier's marine edge, many tied to glacial earthquakes triggered when icebergs break off and collide. This surge coincided with Thwaites accelerating toward the ocean, a correlation that sharpens our focus on how shifting ocean conditions destabilize ice. It is a measurable reminder that what happens below the surface dictates what changes above it. For deeper context on these dynamics, our piece on real-time ocean simulations offers a complementary view.
