Regional strain rate may play as significant a role as temperature in governing the depth distribution of earthquakes in mantle lithosphere.Read More �
The history of river system in southeast Tibet and Indochina reconstructed using the ages of thousands of zircon sand grains in modern and ancient river sediments.Read More �
A new study of small impact craters at Mars landing sites suggests that active processes degrade and infill depressions at similar rates in locations separated by thousands of kilometers.Read More �
Machine learning and data on aquifer type, sediment thickness, and proxies for irrigation water use has been used to produce the most comprehensive map of land subsidence in the western U.S. to date.Read More �
Increments of melt trapped in crystals reveal upper crustal magmas in the Main Ethiopian Rift are rich in water and other volatiles, leading to extensive diffuse degassing and hydrothermal systems.Read More �
A peak in seismic P-wave - S-wave velocity ratios at the lithosphere-asthenosphere boundary beneath old Pacific lithosphere requires an additional property besides temperature as an explanation.Read More �
Tropical cyclones can inject potential vorticity directly into ocean eddies—an alternative way for tropical cyclones to leave fingerprints on the ocean besides the traditional near-inertial wave.Read More �
An international armada of orbiting satellites and ground VLF network join forces to form a “magnetosphere-ionosphere observatory” to size up electromagnetic ion cyclotron waves in the magnetosphere.Read More �
The Lagrangian method applied to tracking water transport between the Atlantic and Pacific basins reveals a larger contribution by mid-latitude westerly winds across Eurasia than previously thought.Read More �
