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.

A New, Underground Atlas of Subduction Zones
Submap merges graphic design with geodynamics, providing a fast, free, and user-friendly resource to map subduction zones.
Talc May Make Mexico’s Subduction Zone More Slippery
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.
Mounds of Ancient Ocean Floor May Be Hiding Deep in Earth
A mysterious seismic feature at the bottom of Earth’s mantle is more widespread than previously thought.
Are Low-Frequency Earthquakes Just Slow Slip?
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 Reveal Phytoplankton Increase at Ocean Fronts
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 Along the Apennines Reflects Subduction Dynamics
Topography and exhumation vary strongly along the Apennines, reflecting the geometry of the Moho and different geodynamic mechanisms.
The Crust Travels to the Earth’s Core and Back in Record Time
Subduction of continental crust around the Gondwana supercontinent may explain the mantle Dupal anomaly of the southern hemisphere.
Tracing Oxidizing Slab Fluids in Cold Volcanic Arcs
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.
