AI reveals hundreds of hidden earthquakes deep beneath East Antarctica
AI-driven reanalysis of two decades of seismic data from 49 stations uncovered more than 500 previously unknown earthquakes about 60–90 miles (100–150 km) beneath David Glacier in East Antarctica. These intermediate-depth quakes (magnitude 1.6–3.5) occur far from plate boundaries, suggesting a more seismically active interior Antarctica and potentially prompting a reevaluation of continental tectonics. The study, published in Science, also highlights AI’s power to reveal hidden seismic activity in other regions, while not posing a threat to the ice sheets.
