While we can’t predict exactly when the next Great Cascadia Earthquake will happen, we CAN forecast the probabilities from a long history of past earthquakes. The study of the geological history of the last 10,000 years of the Cascadia Subduction Zone has shown that there have been 43 great earthquakes (magnitude 8.0 or higher) along the coast of Oregon, Washington, California, and British Columbia. It’s likely that some of these earthquakes were magnitude 9.0 or higher, and as with the 2011 Japanese and 2004 Sumatran earthquakes, they probably also caused large tsunami waves that were devastating all over the Pacific. At this Science on Tap, Chris Goldfinger, PhD, professor of geology and geophysics at Oregon State University, will talk about the geology of Cascadia and his research on the recurrence interval of major earthquakes. While this research may not allow us to pinpoint a date for the next great quake, a better understanding of the geological forces at work can help us prepare.
