Beneath the Pacific Northwest lies the Cascadia Subduction Zone a 600 mile fault capable of producing magnitude 9 earthquakes and massive tsunamis. The last rupture in 1700 shook the region for ...

Deep-sea landslides in the Pacific Northwest's Cascadia subduction zone hold a record of earthquakes dating back 7,500 years, and similar markers may be found in other tectonic plate boundaries ...

The West Coast of North America is a geologically tumultuous zone where tectonic plates collide, subducting under and scraping past one another. Over the eons, this activity has regularly caused major ...

If the Cascadia subduction zone and the San Andreas fault can act in concert, then seismic models must consider the possibility of coupled behavior. That could mean a higher short-term risk of back-to ...

CORVALLIS, Ore. – 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 ...

It was a groundbreaking discovery. Scientists have found previously concealed fault lines along California’s north coast, sparking concerns that we could be drastically underestimating the earthquake ...

It’s like a plot from a Hollywood movie. A massive earthquake on one West Coast fault triggers other earthquakes far away, causing vast destruction over hundreds of miles. A new study released Tuesday ...
