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

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

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

One of these hidden plates was found underneath the western Pacific. However, there is no evidence of plate subduction—a geological process in which one tectonic plate is forced beneath another ...

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 ...

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

Caption The Cascadia Subduction Zone is capable of generating powerful earthquakes. The study found compact sediments along the coast of Washington and northern Oregon, a result that suggests that ...

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

Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme pressure and heat ...

More specifically, subduction zones — where tectonic plates slip over and under each other — can push land to open or close oceans. Researchers found that an inactive subduction zone under the ...

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