January 26 marked the 325th anniversary since the last earthquake struck the Cascadia subduction zone. Centuries later, the ancient quake has left clues for scientists to prepare for the next one.

Earthquake experts say current building codes don’t reflect the riskiest features of the Seattle area’s geology — but the outlook for survivability looks a lot better if the Really Big ...

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

This area, called the Cascadia Subduction Zone, hosts a megathrust fault, a place where tectonic plates move against each other in a highly dangerous way. The plates can periodically lock up and ...

Its eruption won’t trigger a tsunami or a massive land-based earthquake because of its depth and its distance from the region’s megathrust Cascadia fault. But scientists can use the lessons ...

"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 ...

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.

The 71 km 2 Macks Property was staked by Cascadia in 2023 ... and is adjacent to the 200 km dextral strike slip Braeburn fault. The Stikine Terrane is characterized by Late Triassic to early ...
