Summary
Hundreds of previously unknown earthquakes were identified beneath Antarctica’s David Glacier, with magnitudes of 1.6 to 3.5 and depths exceeding 43 miles, according to a new Science paper.
Deep-learning analysis of seismic data from 2001-2004 and 2012-2015 uncovered the events, which sit below the crust-mantle boundary and fall outside the usual plate-boundary pattern.
The team linked the quakes to bending stresses where cold, rigid East Antarctic lithosphere meets warmer, softer rock beneath West Antarctica, creating an abrupt shift in tectonic strength.
The findings suggest Antarctica is more seismically active than thought and that similar intraplate intermediate-depth earthquakes may be more common globally if AI-based detection is applied elsewhere.

If 'stable' Antarctica is seismically active, are any of Earth's continents truly safe from deep earthquakes?
Hundreds of Hidden Deep Earthquakes Discovered Beneath Antarctica: How AI Is Redefining Global Seismic Risk and Ice Sheet Stability
Overview
A groundbreaking discovery beneath Antarctica’s David Glacier has revealed hundreds of previously hidden earthquakes, overturning the long-held belief that the continent is largely free of seismic activity. This surprising finding, made possible by Long Ho and his team using advanced deep-learning seismic detection methods, identified numerous intraplate intermediate-depth earthquakes in an area once considered quiet. The sheer number of these events astonished researchers and has prompted further investigation into their global significance, marking a major shift in scientific understanding of Antarctic seismicity and opening new avenues for research into hidden earthquakes worldwide.
