Landslides, earthquakes, and subduction faults could generate 1,000-foot mega-tsunamis, wiping coastal communities off the ...

The Cascadia Subduction Zone, dormant for over 300 years, poses a significant threat to the Pacific Northwest. A future earthquake, potentially magnitude 8.0 or greater, carries a 15% chance of ...

Cascadia scenario: Given its proximity to the Cascadia subduction zone, Del Norte County — the state's northernmost coastal region — is perhaps more exposed to tsunami risk than any other part ...

For the Cascadia Subduction Zone, the geological record shows a pattern of megathrust quakes occurring roughly every 250 to 800 years. “We’re over 300 years out from the last earthquake ...

Known as the Cascadia Subduction Zone, this 1,130-kilometer-long (700-mile-long) fault line extends from around Cape Mendocino in California up to near Vancouver Island, Canada.

The big one — a magnitude 9.0+ Cascadia Subduction Zone earthquake — could happen any time now based on its history. An analysis out of Virginia Tech and the University of Oregon shows a dramatically ...

This is called the Cascadia Subduction Zone. According to the Washington State Department of Natural Resources (DNR), earthquakes happen in Washington every day, but most are too small to be felt.

The Cascadia Subduction Zone, stretching from northern California to British Columbia, is one of the most dangerous seismic hotspots in North America, capable of producing a massive 9.0 magnitude ...

The 1980 eruption cycle made Mount St. Helens one of the most famous volcanoes in the Cascades. But it is far from the only volcano in the range.
