Wow.

Keep safe, everyone.

A Tsunami Advisory is now in effect for coastal areas of California, including Humboldt, Del Norte, and Mendocino counties, after a powerful 8.8 magnitude earthquake struck off the east coast of Russia’s Kamchatka Peninsula at 3:24 p.m. PDT today. [Note the earthquake has been reevaluated to be of higher magnitude than earlier stated.

According to the National Weather Service in Eureka, the first wave arrival is expected around 11:50 p.m. PDT, and multiple waves may continue for 10 to 36 hours. Residents are strongly urged to stay off beaches and out of harbors and marinas until the advisory is lifted.

“Mariners are advised to get to a depth of 30 fathoms (180 feet) before wave arrival,” the NWS warned. “For Humboldt Bay, that depth lies about 12 miles from the marina.” People should continue monitoring official updates throughout the evening.

The Redwood Coast Tsunami Work Group advises, “This is not a good night to go on a midnight fishing trip or sleep on the beach, but the impacts will be restricted to areas below the high tide level. ”

We're (Santa Cruz, Calif.) under a watch right now, as we were after the 9.1 Tohoku, Japan quake in 2011. When that tsunami got here hours later, it had weakened to six inches. Boats in the harbor were sloshed around a bit, and water came onto the lowest part of East Cliff Drive, which is pretty much at sea level.

I'm not saying "Don't worry about it," but the likelihood of any damage to the California coast is quite low. I dunno about northern Oregon or Washington.
