Aftershocks From M6 Earthquake Rattle California, Nevada

Aftershocks have hit the region between Northern California and Nevada Friday after a magnitude 6 earthquake sent large boulders rolling into highways and knocked smaller items off shelves.

The quake shortly before 4 p.m. Thursday was centered south of Lake Tahoe near Walker, a rural community of a few hundred households in the eastern Sierra Nevada. It was felt as far off as Las Vegas and San Francisco, authorities said. Days of aftershocks are expected.

California state emergency crews worked overnight and found minor road damage but no significant impacts to infrastructure, said Brian Ferguson, spokesman for the California Governor’s Office of Emergency Services. No injuries were immediately reported.

California Quake Alerts Will Come Standard on Android Phones

California’s earthquake early warnings will be a standard feature on all Android phones, bypassing the need for users to download the state’s MyShake app in order to receive alerts, the Governor’s Office of Emergency Services said.

The state worked with the U.S. Geological Survey and Google, the maker of Android, to build the quake alerts into all phones that run the commonplace operating system. The deal was expected to be announced Tuesday.

Scientist Says Chances of Big One on San Andreas Greater Than We Believed

Get ready for the big one.

That’s a refrain Californians have heard for years, but this time one scientist is putting a number on it.

There’s a 1% chance a big quake will strike next year on the Southern section of the San Andreas Fault, according to Ross S. Stein, Ph.D., CEO of Temblor Inc., a catastrophe risk modeling company based in Redwood City, Calif.

That may not sound that high, but it’s a lot higher than previously believed.

Magnitude 4.9 Earthquake Confirmed in Southern California

An earthquake with a preliminary magnitude of 4.9 rattled much of inland Southern California on Friday evening but no damage or injuries were reported, the U.S. Geological Survey confirmed.

The quake struck just after 6:53 p.m. and was centered near Anza in a remote desert area of Riverside County, southeast of Los Angeles and not far from Palm Springs. However, it was felt as much as 100 miles from the epicenter, according to a U.S. Geological Survey website.
