The seismic data collected by the Initiative has also helped Gao and her colleague Yang Shen at the University of Rhode Island, along with another study by Columbia University scientist Helen Janiszewski and Cornell University researcher Geoffrey Abers, to compile a picture of the CSZ structure that points to new places where the crushing pressure of subduction is squeezing water from and transforming rock at the trench where the Juan de Fuca plate is bending under the North American plate.

A new study led by The University of Texas at Austin has found that the occurrence of these big, destructive quakes and associated devastating tsunamis may be linked to compact sediments along large portions of the subduction zone.

The study, published in Journal of Geophysical Research: Planets, uses computer modeling to show that subduction — when a tectonic plate slides underneath another and sinks deep into a planet's interior — is physically possible in Europa's ice shell.

Intriguingly, the part of the subduction zone that broke was not the part that had built up the most stress, according to a ground - motion study of northern Chile's seismic gap by Marianne Métois, a geophysicist at the National Institute of Geophysics and Volcanology in Rome, and her colleagues (M. Métois et al.Geophys.

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 P. P. Shirshov Institute of Oceanology in Moscow proposes to study ocean rift zones, subduction zones, and the sites of nuclear and toxic waste dumps.

A new study suggests that the common belief that the Earth's rigid tectonic plates stay strong when they slide under another plate, known as subduction, may not be universal.

By studying the speed at which seismic waves travel in different directions through the same material, a phenomenon called seismic anisotropy, the researchers found that interior of the Nazca plate had been deformed during subduction.

Thus, the study could improve the understanding of the geochemical processes in subduction zones of the earth.

The study, published February 12 in Nature Geoscience, focused on the Costa Rica subduction zone where the Cocos plate slowly dives beneath the overriding Caribbean plate.

The study site, Stardust Bay, faces a creeping part of the eastern Aleutian Subduction Zone, which is sandwiched between the rupture areas of historical earthquakes in 1946 and 1957 that generated tsunamis with devastating consequences to coastal communities around the Pacific Ocean.

The first study suggests Europa's surface, like Earth's, undergoes a process of subduction, wherein one tectonic plate moves under the surface of another and sinks due to gravity.

Though a previous geological study by Louise Prockter and Simon Kattenhorn made the case that something like subduction could be happening on Europa, it wasn't clear exactly how that process would work on an icy world..
