The Shaken Coast: New Research Highlights Oregon's Earthquake Risks The Pacific Northwest has long been a seismically active region, but new research suggests that northern Oregon may be more vulnerable to the next Cascadia megathrust earthquake than previously thought.
A recent study by seismologists from the US Geological Survey and the Seismological Society of America found that the Juan de Fuca plate beneath northern Oregon is shallower than estimated, potentially increasing the intensity of shaking in populated areas.
This finding challenges long held assumptions about the Cascadia subduction zone.
