Hundreds of deep earthquakes have been detected beneath Antarctica using machine learning, according to a study published in Science. Researchers identified over 500 intraplate intermediate-depth earthquakes (IDEs) at depths of 100-150 kilometers, challenging traditional plate tectonic theories. The findings, reported by multiple outlets, reveal Antarctica’s unexpected seismic activity and raise questions about the limits of current geological models.
Discovery of Deep Quakes Under Antarctica
Scientists have uncovered over 500 previously unknown earthquakes beneath East Antarctica, primarily beneath the David Glacier, according to a study published in *Science*. The quakes, detected using machine learning algorithms, occur at depths of 100 to 150 kilometers—far below the Earth’s crust and into the upper mantle. This region, not located near tectonic plate boundaries, defies conventional seismic expectations. “Intraplate earthquakes challenge the traditional plate tectonic paradigm,” the researchers wrote, noting that such events are rare and poorly understood. ScienceAlert reported the study’s findings, which were also covered by Live Science.

Methodology: AI and Seismic Analysis
The research team analyzed seismic data from 49 monitoring stations across East Antarctica, spanning two periods: 2001–2004 and 2012–2015.
