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 ...

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 ...

PORTLAND, Ore. (KOIN) – A new study mapping the Cascadia Subduction Zone is giving scientists clues about the state of the ...

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.

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

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 ...

January 26 marked the 325th anniversary since the last earthquake struck the Cascadia subduction zone. Centuries later, the ancient quake has left clues for scientists to prepare for the next one.

A 4.2 magnitude earthquake struck about 143 miles southwest of Tofino, B.C., at around 5:53 a.m. A second 3.0 magnitude ...

Researchers found that an inactive subduction zone under the Strait of Gibraltar may begin migrating into the Atlantic Ocean, commencing the shrinking process. The zone also brings a higher risk ...

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

The new bridge will be earthquake-ready, so crews are digging a 10-foot-wide, 125-foot-deep hole to see how concrete supports react during a simulated seismic event.
