Oregon Earthquakes
From: Mail Tribune
After studying everything from “ghost forests” submerged after a tsunami to undersea landslides, scientists have determined that 40 earthquakes magnitude 8 or larger have struck Western Oregon in the past 10,000 years.
“And they found that 75 percent of those have happened less than 310 years apart on the average,” Roddey said. “That suggests we are due, and due sooner rather than later.”
