Summary
More than 500 previously unrecognized earthquakes were found beneath East Antarctica after researchers used machine learning to reanalyze data from 49 seismic stations collected between 2001-2004 and 2012-2015.
Those quakes occurred 100 to 150 kilometers below David Glacier, a surprising mid-plate location because intermediate-depth earthquakes are usually associated with subduction zones at tectonic plate boundaries.
The study says stress builds where cold, rigid East Antarctic crust meets warmer, softer rock beneath West Antarctica, while buoyant upper-mantle material bends the nearby crust and triggers shaking.
Magnitudes ranged from 1.6 to 3.5, too small to threaten the overlying ice sheet, but the findings suggest Antarctica is more seismically active than thought and that similar hidden quakes may exist elsewhere.

AI Reveals 500+ Previously Undetected Deep Earthquakes Beneath Antarctica, Challenging Assumptions of Geological Stability
Overview
Antarctica was long thought to be a quiet and geologically inactive continent, but recent advancements in seismic analysis have revealed a hidden world of seismic activity beneath its ice. This marks a major shift in our understanding, as over 500 previously undetected earthquakes were discovered beneath the David Glacier in East Antarctica. These earthquakes, though modest in magnitude, had gone unnoticed by traditional methods. The discovery fundamentally changes how we view Antarctica’s stability and internal processes, showing that the continent is far more dynamic and complex than previously believed.
