6.5 Earthquake Off The Northern California Coast !Updated!


At 4:27 this afternoon a 6.5 quake hit 27 miles off the coast of Eureka. That’s a fairly big shaker and we felt it here well over 200 miles inland. There were a few shakers in the 3-4 range in San Francisco earlier this week and the epicenter of this one is at the end of the San Andreas fault where it meets the Pacific and American plates in the Cascadia subduction zone. There have been several aftershocks but no threat of a tsunami.

All the technical details and a map are HERE.

!UPDATE! Some minor damage, injuries and power outages.

Dozens of people suffered minor injuries and thousands lost power.

In Eureka, north of Ferndale, residents of an apartment building were evacuated, and an office building and two other commercial structures in the town of about 26,000 people were declared unsafe for occupancy, according to Humboldt County spokesman Phil Smith-Hanes.

“Our initial reports were that, though this was a pretty decent quake, we survived it well,” Smith-Hanes said, adding that damage assessments would continue Sunday across the county.

Sandra Hall, owner of Antiques and Goodies, said furniture fell over, nearly all her lamps broke and the handful of customers in her store got a big scare. She said it was the most dramatic quake in the 30 years the Eureka store has been open.

“We’ll be having a sale on broken china for those who like to do mosaics,” she said.

More than a dozen aftershocks, some with magnitudes as powerful as 4.5, rumbled for several hours after the initial quake, which had a depth of nearly 10 miles.

  1. I had been looking at the fault map and trying to decide which fault, if any, it had been along. Seemed to me to be between the fault line and Cascadia subduction zone, but I really couldn’t tell. Thanks for the update.

  2. There’s two major plates and a wicked fault line that all meet there. Quite the party place for quakes. San Andreas stops just south of there. http://neic.usgs.gov/neis/eq_depot/2010/eq_100110_nc71338066/nc71338066_h.html

  3. Thanks, that’s a much better picture of the relationship between the earthquakes/fault lines!
