A new geological study suggests that California’s San Andreas Fault and the Cascadia Subduction Zone, two of the most ...

These are two very different fault systems, but the sediment record suggests that in the past, at least three San Andreas ...

Newly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present along the Cascadia Subduction Zone is missing in places. What does that mean ...

29. For example, researchers found evidence that the last magnitude 9 earthquake in the Cascadia subduction zone - in 1700 ...

Two fault systems on North America’s West Coast – the Cascadia subduction zone and the San Andreas fault – may be synchronized, with earthquakes on one fault potentially triggering seismic events on ...

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 disaster caused by a predicted large earthquake in the Pacific Northwest could be compounded by shaking along the San Andreas fault in California, scientists warned.

Scientists at Oregon State University say there's new evidence that two of the best-known earthquake fault lines on the West ...

(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

The Pacific Northwest is known for its towering trees, beautiful landscapes and breathtaking coast. But what sits about 70 miles off that coast, and anywhere from 300 to 10,000 ft below the ocean's ...
