Hundreds of hidden earthquakes discovered beneath Antarctica — and they're happening in a very odd location

Scientists Detect Hundreds of Earthquakes Deep Beneath Antarctica

Something is stirring deep beneath the thick sheet of ice blanketing Antarctica. With the help of deep learning algorithms, scientists have discovered hundreds of previously unknown small earthquakes under the David Glacier, an enormous shelf that stretches almost 700 mile, as detailed in a new paper published in the journal Science. The team analyzed two existing datasets that range from 2001 to 2004 and 2012 to 2015. The quakes themselves were…

Hundreds of hidden earthquakes discovered beneath Antarctica — and they're happening in a very odd location

Antarctica was long thought to be seismically calm, but new technology makes it possible to detect unexpected types of earthquakes beneath the ice.

Deep learning helps discover hundreds of Antarctic earthquakes coming from an unlikely location

Most of the earthquakes we hear about are due to tectonic plates colliding or sliding past each other near plate boundaries. Yet researchers have detected some enigmatic earthquakes happening inside the more stable interiors of plates. Intermediate-depth earthquakes (IDEs), which occur around 70–300 kilometers (43–186 miles) below the surface, are especially puzzling because rocks at those depths are hot enough to flow more fluidly.
