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 ...

In a groundbreaking study published in Science Advances (2025), scientists uncovered a fascinating and unusual process ...

Scientists at Oregon State University say there's new evidence that two of the best-known earthquake fault lines on the West Coast are in sync and that has the potential for a major disaster. One of ...

Researchers have conducted detailed structural analyses of a fault zone in central Japan to identify the specific conditions that lead to devastating earthquake. The seismic slip processes that were ...

With unprecedented clarity, scientists have directly observed a subduction zone—the collision point where one tectonic plate dives beneath another—actively breaking apart. The discovery, reported in ...

It’s the 323rd anniversary of the last Cascadia Subduction Zone earthquake. We spend a fair amount of time thinking about the ‘Big One’ (and the ‘Really Big One’) in the Pacific Northwest. Today is ...

The study out of Oregon State University shows two major faults -- the San Andreas and the Cascadia Subduction Zone -- could ...

A major earthquake along the Cascadia Subduction Zone could cause coastal land from to sink permanently, dramatically increasing the risk of flooding, according to a new study. The research, published ...

The Portland City Council voted on Wednesday to limit the expansion of fossil fuel terminals in the city. Mayor Ted Wheeler said the move will bolster Portland’s efforts to combat climate change and ...

PORTLAND, Ore. (KOIN) — Friday’s 4.4 earthquake in Linn County is an excellent reminder for Pacific Northwest residents to prepare for the potential 9.0 “megathrust” earthquake that could occur along ...
