Combining the 19th - century records of such effects with modern earthquake models helped Beauducel and Feuillet pin down both the quake's magnitude and the location of the fault rupture, the spot where the subduction zone tore apart.

Many of the islands sit above a subduction zone, where two plates meet and one slides haltingly under the other, down into the Earth's mantle.

Events of this magnitude normally occur in a subduction zone, where one tectonic plate slides beneath another.

The Tohoku - Oki earthquake occurred in a «subduction zone,» a boundary between two tectonic plates where one plate is diving beneath another — in this case, the Pacific plate dives beneath the Eurasian plate just east of Japan.

The strain that is released in a subduction zone earthquake is thought to build up in the deep portion of the fault where the two plates are «locked.»

It's the first time this tectonic process has been discovered beneath land; all other known subduction zones occur underwater where oceanic crusts meet.

The surface where they slip is called the fault, and the system of faults comprises a subduction zone.

With these plate tectonic reconstructions Schellart was able to predict where the fossil subduction zone was during its lifetime some 50 - 70 million years ago, and therefore where the lithospheric slab disappeared into the mantle.

This predictability most likely stems from the fact that water flowing from below subduction zones may exert significant control over when and where these faults slip silently.

(A subduction zone is where one tectonic plate sinks below another.)

Ward modeled the effects of a magnitude 9.2 earthquake in the Cascadia subduction zone — a 58,000 - square - mile region in the Pacific from British Columbia to Northern California where the Juan de Fuca plate sinks beneath the North American plate.

The team will focus on the Sunda subduction zone, where the Indo - Australian plate goes beneath the Sunda plate.

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

Scientists have long thought diamonds could form in subduction zones, where one tectonic plate plunges under another and sinks hundreds of kilometers into the mantle.

The Sea of Okhotsk rests above a subduction zone, a place where one of the Earth's tectonic plates slides beneath another.

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

There it will seek out new species and habitats; it may also study subduction zones, where oceanic crust is recycled back into the earth's mantle.

Lead author of the study, Dr Caroline Eakin, Research Fellow in Ocean and Earth Science at the University of Southampton, said: «The process of consuming old seafloor at subduction zones, where great slabs of oceanic material are swallowed up, drives circulation in the Earth's interior and keeps the planet going strong.

The earthquake occurred along a 500 - kilometre segment of the Peru - Chile subduction zone, where part of the Nazca Plate in the Pacific Ocean plunges beneath the South American Plate.

The subduction zone along the western edge of South America, where the Nazca plate slides eastward beneath the South American plate at an average rate of about 6.5 centimeters per year, can indeed generate massive quakes.

«Normally mountains arise where you've smashed continents together, or from volcanoes or subduction zones,» she says.

Such a fracture, says Duarte, is evidence of an «embryonic subduction zone,» where a new edge is formed, then forced under the remainder of the plate, into the Earth's molten mantle.

For example, waves move slower when passing through hot magma, such as mantle plumes and hotspots, than they do when passing through colder subduction zones, locations where one tectonic plate slides beneath another.

Researchers hope to use similar imaging techniques on other subduction zones, such as the Cascadia margin along the northern U.S. west coast, where there is a long history of large megathrust earthquakes and related tsunamis.

On Earth, as new surface material forms at mid-ocean ridges, old material is destroyed at subduction zones, which are regions where two tectonic plates converge and overlap as one is forced under the other.

Last week's temblor may have relieved pressure in one of two «seismic gaps» in the subduction zone off Mexico's coast, where tectonic plates grind past one another.

Geologically speaking, Cascadia is a classic subduction zone, where one plate of Earth's crust plunges beneath another, building up stress and occasionally relieving it in large earthquakes.

That variety implies that almost any scenario is possible in another part of the Pacific Rim where quake risk is thought to be high — along the Cascadia subduction zone offshore of Washington, Oregon, and other parts of the western United States and Canada.

Scientists have been attracted to the region because of the subduction zone located at the bottom of the ocean where the Pacific and North American tectonic plates collide, the Aleutian Trench.

Near subduction zones, plates collide, forcing ocean crust down toward Earth's hot interior, where this crustal material melts, forming magma that rises buoyantly back to the surface and erupts to create volcanoes and seamounts.

The Cascadia subduction zone lies offshore from northern California to southwestern British Columbia, where two tectonic plates — the North America plate and the Juan de Fuca plate — come together to form an 800 - mile long earthquake fault.

The research programme will investigate the geological processes that occur at subduction zones - regions of the Earth's crust where one tectonic plate descends beneath another, generating volcanoes and earthquakes.
