Why do we need a new I-5 bridge? "Pressure is mounting for another Cascadia Subduction Zone megathrust. At risk are the two ...

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

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

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

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

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

Jiaqi Fang and colleagues describe a new subduction model that can better capture both long-term tectonics and short-term earthquakes and that agrees with existing observations. The model combines ...
