(KOIN) – A new study mapping the Cascadia Subduction Zone is giving scientists clues about the state of the fault line as the ...

The quake serves as a reminder of the long-term seismic risks posed by the Cascadia Subduction Zone, a less-publicized but potentially catastrophic fault system that extends from Northern ...

Hidden off the US Western shore, beneath the Pacific Ocean, is the Cascadia Subduction Zone. This fault is capable of generating earthquakes larger than magnitude 8 that can be felt hundreds of ...

The Cascadia ... earthquakes, Schulz writes: Yet not once in recorded history has it caused a major earthquake - or, for that matter, any quake to speak of. By contrast, other subduction zones ...

(AP Photo/Rick Bowmer, File) PORTLAND, Ore. (CN) — It’s not a question of if, but when: A megathrust earthquake will someday occur along the subduction zone that lies beneath the Pacific Northwest. In ...

"the big one" — a magnitude 8.0 or higher earthquake — is imminent from the Cascadia Subduction Zone off the coast. Experts say there is a one-in-three chance that a magnitude 8.0 or higher ...

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed for powerful quakes, with a particularly strong one called the Big One ...

Scientists now believe there have been at least 19 major, megathrust earthquakes triggered at the Cascadia Subduction Zone in the past 10,000 years. But the data is still too sparse, said Diego ...

In contrast, the Cascadia Subduction Zone, which extends from northern California to southern British Columbia, has a greater potential to produce a large tsunami, experts warn. This is because a ...
