A new study demonstrates the absorption mechanism of H2O release out of subducting slabs, making the previous hypothesis of dehydration embrittlement unnecessary.
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.
Submap merges graphic design with geodynamics, providing a fast, free, and user-friendly resource to map subduction zones.
Production of the weak, water-bearing mineral at the interface between the Cocos and North American Plates could contribute to the occurrence of poorly understood episodic tremor and slow slip.
A mysterious seismic feature at the bottom of Earth’s mantle is more widespread than previously thought.
Tests of seismic attenuation show fluid saturation and high pressure near a seismic source reduce high-frequency content, challenging the idea of slow slip as the cause of low-frequency earthquakes.
Bio-Argo floats and satellite altimeter data reveal that upwelling caused by confluent flow on the warm side of ocean fronts increases phytoplankton carbon and chlorophyll.
Topography and exhumation vary strongly along the Apennines, reflecting the geometry of the Moho and different geodynamic mechanisms.
Subduction of continental crust around the Gondwana supercontinent may explain the mantle Dupal anomaly of the southern hemisphere.
Elevated copper isotope ratios in arc magmas from fluid-rich cold subduction zones support the role of oxidizing fluids from the subducted lithospheric serpentinite in the oxidization of arc magmas.
