Is the Big One coming to Oregon?

SALEM, Ore. (AP) — People in Oregon will be better prepared for earthquakes — particularly important in the Pacific Northwest because experts say “the big one” is coming — as an early warning system launched Thursday, the 10th anniversary of a devastating quake and tsunami in Japan.

Is the Cascadia earthquake coming?

Will Oregon be affected by San Andreas Fault?

Yes. It’s not a matter of if, but when. The Pacific Northwest is commonly known to be the most dangerous earthquake hotspot outside of California. So while the San Andreas Fault Line is a well known danger to Californians, Pacific Northwesterners also need to be prepared!

Would Portland be hit by a tsunami?
