Thanks to the Great Oregon ShakeOut drill, earthquakes are top of mind for Oregonians, but why should we prepare? Frequently ...

A subduction zone is created where two plates converge, with one sinking into the mantle. Dynamics along the plate interface create earthquakes, magma generated above the sinking slab leads to ...

Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 ...

地质历史上的碳循环在控制地球气候和维持地球宜居性方面发挥着关键作用。作为地球上最大的物质循环系统，俯冲带调节着地球内部与地球表层之间的碳交换，对全球长期的碳循环起着重要控制作用。板块俯冲通过沉积物、蚀变洋壳和蛇纹石化橄榄岩，将大量无机碳和有机碳输送到 ...

At approximately 5:58 p.m., PST yesterday, October 17th, a 5.0 magnitude earthquake (6 miles deep) struck just off the coast ...

A new algorithm used to analyze sediment layers of the seafloor is helping scientists pinpoint the timing of past Cascadia ...

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.

The final threat of earthquakes in the Northwest comes from volcanic activity. The moving magma beneath the earth’s surface ...

Well-controlled uniaxial and simple shear deformation experiments were conducted on Mg-endmember phase D and Al-bearing phase ...

“The day it releases all that tension, all that stress is just released, the plate lifts up, pushes the water out of the way, ...

Researchers from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS), along with collaborators from ...

The Hikurangi Subduction Zone - where the Pacific and Australian plates meet offshore and beneath the North Island - poses New Zealand’s single largest earthquake and tsunami threat. Image / GNS ...
