Stanford Maps Deep Earthquakes in Mantle

Scientists at Stanford University have achieved a groundbreaking feat by mapping rare mantle earthquakes. By delineating hundreds of these deep tremors, they revealed significant clusters beneath the Himalayas and near the Bering Strait. The research, published in Science on February 5, provides new insights into the crust-mantle boundary and the behavior of Earth's upper mantle. Though these deep-seated earthquakes do not cause damage due to their remote origins, they offer valuable understanding of common earthquake mechanisms. Using innovative seismic wave detection, researchers distinguished mantle quakes from those in the crust. From over 46,000 recorded tremors, they identified 459 mantle earthquakes since 1990. Future studies are expected to further uncover the intricate workings of Earth's geological systems.
