January 26 marked the 325th anniversary since the last earthquake struck the Cascadia subduction zone. Centuries later, the ...

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

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 ...

This area, called the Cascadia Subduction Zone, hosts a megathrust fault, a place where tectonic plates move against each ...

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.

One robotics team in Oregon City, Skynet, has worked to get rid of the financial barrier that kept some kids out of STEM programs. A Salem man was arrested Friday for the murder of a woman who was ...

"We're at more than 324 years since the last one." The risk comes from the Cascadia Subduction Zone, which is a fault line that spans approximately 600 miles from southern British Columbia to ...

The biggest danger zones of the seismic variety are the Cascadia Subduction Zone in the Pacific Northwest, the San Andreas Fault in California, and the New Madrid Seismic Zone in Missouri.

When enough stress builds, the fault will rupture, releasing a massive amount of energy. The Cascadia Subduction Zone has the potential for these types of earthquakes and has ruptured in the past.

Two SHIPS seismic reflection lines crossed the Seattle fault zone, which comprises a number of individual fault splays, line PS-1 in the west and line PS-2 in the east close to downtown Seattle (Fig 1 ...
