AI Uncovers Hidden Deep Quakes Beneath East Antarctica
Researchers analyzed data from 49 seismic stations across East Antarctica with a deep-learning detector, identifying about 510 deep, intermediate-depth earthquakes (magnitudes 1.6–3.5) clustered 100–150 km beneath the David Glacier. Occurring far from plate boundaries, these intraplate quakes are likely driven by rock bending from high-temperature mantle and a nearby lithospheric boundary between East and West Antarctica, illustrating how AI can reveal hidden seismic activity.
