Cascadia Subduction Zone

Cascadia Region Earthquake Workgroup

An ominous anniversary looms at the end of the month: the 316th anniversary of the last major Cascadia earthquake (January 26th). 

On average, the Cascadia Subduction Zone ruptures about every 240 years... so we're due for a big shake. 

University of Oregon geophysicist Doug Toomey is involved with the Cascadia Initiative, a project to better understand the mechanics of the subduction zone.

People on the West Coast have been talking for years about the pending earthquake in the Cascadia Subduction Zone.

It took ONE article in the New Yorker to sweep through social media and rekindle the quake concerns. 

And they are well-placed... damage from a Cascadia quake would rattle the ground and everything on it, likely from California to British Columbia. 

Geologists say one could happen at any time.

It's not an anniversary anybody celebrated, and it certainly is not one anyone wants to re-enact. 

But January 26th marked 315 years to the day since the last big earthquake along the Cascadia Subduction Zone. 

Scientists tell us that time gap means Cascadia is due, if not overdue, for another major shaking. 

Oregon Emergency Management continues to warn of the likely destruction by such a quake.

What's in your earthquake kit?

The answer to that question is often "uh, I don't have one yet."  Which is why Oregon's Office of Emergency Management is hosting the Quake Prep Talk Road Show, visiting counties in the southern and southwestern portions of the state--the places most likely to feel the impacts of a major quake along the Cascadia Subduction Zone.
