At a destructive boundary the plates are moving towards each other. This usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate.

A team of geophysicists at ETH Zurich in Switzerland has made a baffling discovery while analyzing earthquake waves to ...

Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth. Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

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.

But far away from these plate boundaries, at the center of oceanic plates, scientists thought that large sections of Earth's crust remained fairly rigid as they drifted atop the mantle ...

The Pontus oceanic plate that was reconstructed by Suzanna van de Lagemaat: its location in the paleo-Pacific ocean 120 million years ago, and its present relicts. An earlier study showed that a ...

A Nankai Trough megaquake is expected to strike along the boundary between a continental plate and an oceanic plate. But the Jan. 22 temblor occurred inside the oceanic plate, which lies at a ...
