There was a 6.5 magnitude earthquake about 3.5 hours ago offshore of Eureka, California, but the Pacific Tsunami Warning Center says there is no threat of tidal waves.
KTVU.com has some pretty good coverage, including photos. The station reports power outages and property damage but no casualties.
I'm more interested than usual because I grew up just over the border in Southern Oregon. The 1964 Crescent City tsunami was big news in the area, though the reference is misleading in this context.
I've read that 'tsunami' is Japanese for 'harbor wave', and that's basically what hit Crescent City. It sits at the end of a north-facing bay that funneled wave energy from the Great Alaskan Earthquake. Damage from that quake led to the creation of the West Coast & Alaska Tsunami Warning System.
