Seismology
Researchers at Stanford University have developed the first worldwide map of rare earthquakes occurring deep in Earth's mantle, rather than the crust. These elusive events cluster in regions like the Himalayas and near the Bering Strait. The study, published on February 5 in Science, identifies hundreds of such quakes and introduces a new method to detect them using seismic waves.

A new analysis of sediment cores from a Nepali lake reveals that major earthquakes in the central Himalayas occur randomly rather than at regular intervals, challenging fears of an imminent massive quake. Researchers identified at least 50 events of magnitude 6.5 or larger over the past 6,000 years, including eight since 1505. This finding suggests the region has experienced more seismic activity than previously thought.
