|It’s bad enough that die-hard locals know that there are frequent substantial earthquakes off Southern Oregon and Northern California. But they had another respectable earthquake today well offshore of Eureka, California with a Richter reading of 6.2. A respectable earthquake shaker to be sure. The National Weather Service’s Tsunami Warning Center immediately checked out the situation and quickly determined that a 6.2 Richter earthquake was nothing to sneeze at. Many coastal stores and buildings suffered minor damaged south and east of the event.
Another earthquake zone farther north off the California-Oregon Coast is a totally different animal. That earthquake zone, called the Cascadia Subduction Zone, usually shakes the region every 350 years and they’re getting close to that 350 year mark. The next earthquake in that area will likely hit a 9.5 Richter. When that kind earthquake settles back down, the shoreline usually sinks 6 to 15 feet. Those who ride out such a shaker will see terrible destruction in the small towns along the Washington, Oregon and Northern California Coasts. But those who survive it can be rest assured that Cascadia won’t re-erupt again for 275 to 350 years. At least we hope it won’t.
