January 26 marked the 325th anniversary since the last earthquake struck the Cascadia subduction zone. Centuries later, the ...

This area, called the Cascadia Subduction Zone, hosts a megathrust fault, a place where tectonic plates move against each ...

The Earth's surface is constantly reshaped by the movement of tectonic plates, which make up the continental crust on which ...

Now, scientists aim to get their clearest picture yet of the complex mechanics of our big-risk Hikurangi Subduction Zone – and what sets it apart from similar systems around the planet.

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

The modern understanding of the plate tectonic cycle predicts that remnants of submerged plates will be found near subduction zones. However, a new high-resolution model shows that these remnants ...

SNOQUALMIE, Wash. — An earthquake struck near Snoqualmie Monday afternoon, according to the United States Geological Survey ...
