Plates at subduction zones typically move just a few centimeters per year. But when accumulated stress at these convergent plate boundaries releases suddenly, the plates can slip several meters ...

We consider two end-member subduction scenarios: forced and free subduction. In the forced scenario, horizontal velocities are applied to the lateral boundaries of the plates during the entire ...

Motion along this and other megathrust boundaries have been difficult for ... long-term changes occurring at subduction zones. The cycle of sudden earthquakes and slow plate movement makes it ...

One of the most active volcanoes in the world sits just a few hundred miles off the U.S. West Coast, and some scientists ...

The dehydration of the slab subduction process produces metasomatic agents that have important effects ... Some of the upwelling streams pierced the weak tectonic boundary under the buoyancy effect, ...

Over 25 years ago, researchers discovered that some of these deep Earth reverberations pointed to the existence of two ...

However, there is no evidence of plate subduction—a geological process in which one tectonic plate is forced beneath another as they converge at a plate boundary—anywhere near this region.

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Earth's biggest mountains, more than 100 times taller than Mount Everest, have been discovered on the boundary between Africa ...
