Satellite images reveal the fastest Antarctic glacier retreat ever

Hektoria Glacier’s sudden eight-kilometer collapse stunned scientists, marking the fastest modern ice retreat ever recorded in Antarctica. Its flat, below-sea-level ice plain allowed huge slabs of ice to detach rapidly once retreat began. Seismic activity confirmed this wasn’t just floating ice but grounded mass contributing to sea level rise. The event raises alarms that other fragile glaciers may be poised for similar, faster-than-expected collapses.
