They also found isotopic signatures corresponding to other subduction zone rocks such as abyssal serpentinite. "Our research indicates that these giant anorthosites likely originated from the ...

I recently participated in a three-week-long, National Science Foundation-funded research cruise to the Mariana Trench. Our ...

Along this fraught stretch, called the Cascadia Subduction Zone, two pieces of the Earth’s crust slide against each other, building up stresses capable of unleashing a catastrophic 9.0-magnitude ...

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.

Discover interesting facts about how big earthquakes can get, why earthquakes happen, and why they're so hard to predict.

Amid Earth’s mobile tectonic plates, subduction zones arise as regions of intense geological activity and concentrate minerals into ore deposits like gold.

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed for powerful quakes, with a particularly strong one called the Big One ...

Megathrust earthquakes occur when stress at subduction zones is released, causing significant plate slippage. These events disrupt long-term tectonic changes, complicating modeling efforts.
