The complex regional tectonic activity includes movement of three plates: the Caribbean plate that is subducting or being forced beneath Colombia in the north; the Panama block or Panama plate that is colliding with Colombia in the central part of the country; and the Nazca plate, which is an oceanic plate that is subducting beneath the southern part of Colombia from the Pacific.

Deep earthquakes, also called intraplate quakes, take place within the oceanic Juan de Fuca plate (beneath Oregon and Washington) and the Gorda plate (beneath northwestern California) as they subduct beneath the North America plate.

Not exact matches

Often, one plate gets subducted under another and sinks into the mantle beneath, while elsewhere, new rocks rise to the surface.

A new study suggests that instead of a plume of hot mantle that extends down to Earth's core, the real culprit is a subducting tectonic plate that began sinking beneath North America hundreds of millions of years ago.

Now seismologists have identified the «Caldas tear,» which is a break in a slab that separates two subducting plates and accounts for curious features, including a «nest» of seismic activity beneath east - central Colombia and high grade mineral deposits on the surface.

It marks the plate boundary between the subducting Nazca plate and the South America plate, where the oceanic crust and lithosphere of the Nazca plate begin their descent into the mantle beneath South America.

The intermediate - depth regions of the subducting Nazca plate can be segmented into five sections based on their angle of subduction beneath the South America plate.

The team found that the subducting slab — a portion of the oceanic plate that slides beneath a continental plate — is the dominant driving force behind the deformation of the mantle.

Subduction zones are areas where one tectonic plate dives or «subducts» beneath another plate.

Both events occurred along a subduction zone, an area where a tectonic plate dives or «subducts» beneath an adjacent tectonic plate.

The warm Atlantic water was saltier, and therefore heavier and subducted at depth and reached to the bottom, actually heating up beneath a lid of ice and melt water, that prevented the release of heat to the atmosphere.

The research, published in the journal Nature Geoscience, found that the Earth's largest flat slab, located beneath Peru, where the oceanic Nazca Plate is being subducted under the continental South American Plate, may be relatively weak and deforms easily.

Water migrates upwards and causes the top of the subducted oceanic crust to melt, producing magma beneath the Cascade volcanoes.

These great quakes often take place at subducting tectonic plate boundaries, where one plate thrusts beneath another plate, as is the case off the coast of Chile and the U.S. Pacific Northwest.
