Minor Earthquake Confirmed in California High Desert

A minor earthquake struck the Southern California high desert on Saturday and was was felt across the region, the U.S. Geological Survey confirmed.

The USGS reports the 3.9-magnitude earthquake hit an area about 13 miles northeast of Barstow at 11:34 a.m. Saturday.

Authorities said there were no immediate reports of damages or injuries. People reported to the USGS that they felt light shaking as far away as Los Angeles and Indio.

California Has Earthquakes, Wildfires, Floods and Volcanoes

(TNS) - Margaret Mangan didn’t sleep well in the weeks following the Ridgecrest, Calif., earthquakes. The July shaking triggered a swarm of smaller tremors in the nearby Coso Volcanic Field, a cluster of lava domes and cinder cones at the northern end of the Mojave Desert. And it was Mangan’s job to watch for a possible eruption.

“We were pretty much on 24-7 vigilance,” said Mangan, the longtime scientist-in-charge of the U.S. Geological Survey’s California Volcano Observatory.

California Unveils New Earthquake Warning System

California governor Gavin Newsom announced a new state-wide system, created in cooperation with the U.S. Geological Survey, that will provide California residents with an early warning for coming earthquakes. Part of the system is an emergency messaging system that sends text warnings, similar to those that cell phone users already get for floods and missing persons. The other component of the system is a new app called MyShake, which will give people “tens of seconds” advance notice before a quake strikes. If you are in a house, that might be enough time to get to a safe spot away from falling furniture. If you are on the road, it may be enough time to pull off the road or stop before a bridge or tunnel.

Should This Part of California Be Worried About Quakes?

(TNS) - This week marks 30 years since the massive 6.9 magnitude Loma Prieta earthquake hit the Bay Area, killing 63 people, injuring nearly 4,000 and causing extensive damage that left thousands homeless.

Generally, people in this part of the state are not too concerned about quakes. Should they be?

Earthquakes, big and small, are a common occurrence in California. Residents hear reports of them all the time – most recently the 4.5 magnitude quake that hit near Pleasant Grove on Monday. The reports are usually just far enough away from the Yuba-Sutter area that residents tend to think things like that won’t happen here.

How Much Warning Time Will California’s Earthquake App Give?

(TNS) — California Gov. Gavin Newsom is set to unveil the state's new earthquake early warning app, MyShake, at 11 a.m. Thursday, available on iOS and Android on the 30th anniversary of the magnitude 6.9 Loma Prieta earthquake. The announcement will be streamed live.

How much warning would MyShake have provided if an earthquake warning system were available in 1989?
