Antarctica's Hidden Seismic Activity Revealed
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 weren’t very strong, clocking in a
Scientists have identified hundreds of small earthquakes beneath Antarctica using deep learning techniques. The quakes were detected under the David Glacier and occurred at great depths. Their origins challenge traditional understandings of plate tectonics. The study suggests a complex interaction between different parts of the Earth's structure. The earthquakes happened in the middle of tectonic plates, not at their edges. Researchers believe the contrast between cold and warm rock layers contributes to the seismic activity. The findings could lead to a reevaluation of how plate tectonics function. Advanced tools like AI may help identify similar activity in other regions.
This discovery challenges existing geological theories and could change how scientists understand seismic activity in stable tectonic regions.
