The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath the overlying North American plate, extends 1100 km from northern California to northern Vancouver Island.

Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the trajectory and speed of the plates as they plunge deep into ...

Schematic figure of the subduction zone underneath the Kanto region (left) in Japan and the spatial distribution of magnitude 2 to 6 earthquakes on the subduction zone at 60 to 70 kilometers below ...

Scientists have discovered an unusually thick mantle transition zone beneath the Lesser Antilles. This discovery sheds new light on how oceanic plates sink into the Earth's mantle. Variations ...

Electrical resistivity data reveal that subduction-zone fluids exert an important influence on deformation in the region. Where the Earth's tectonic plates meet, they interact in complex ...

Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

The melting curves of carbonated basalt at upper mantle and transition zone pressures are from (Kiseeva et al ... Diamond symbols show schematically where diamond can be produced via subduction of ...

This area, called the Cascadia Subduction Zone, hosts a megathrust fault ... the continental rocks causes the incoming, more pliable oceanic plate to bend and twist to accommodate differences ...

The Pontus oceanic plate that was reconstructed by ... An earlier study showed that a large subduction zone must have run through the western paleo-Pacific Ocean, which separated the known Pacific ...

These metals form in the upper crust at depths of a few kilometers (several miles). But how do they form and why are they concentrated there? (A) Diagram of a subduction zone illustrating the transfer ...

Newly published research has revealed that compositional rock anomalies within oceanic plates caused ... experiment conducted at an Atlantic subduction zone," said Dr. Catherine Rychert, formerly ...
