Los Angeles (AP) — A fire official says there were no fatalities or major injuries in Ridgecrest after the 7.1 magnitudes earthquake on Friday night.

Kern County Fire Chief David Witt also said Saturday there were no major building collapses but some structures could be weakened from the back-to-back quakes.

Friday’s quake occurred a day after a magnitude 6.4 quake hit in the same area of the Mojave Desert about 150 miles from Los Angeles.

Witt says there were some power outages and minor gas and water leaks in Ridgecrest, but no known damage outside the area.

Fire officials say as many as 50 structures in the small town of Trona were damaged by the magnitude 7.1 earthquake Friday night in Southern California.

In addition, San Bernardino County Supervisor Robert Lovingood said Saturday that damaged water lines prompted FEMA to deliver a tractor-trailer full of bottled water to the town, and firefighters were checking numerous reports of gas leaks.

The town was temporarily cut off after the earthquake, when officials shut down a highway connecting Trona to Ridgecrest because of rockslides and cracks in the roadway.

Julia Doss, who maintains the Trona Neighborhood Watch page on Facebook, said residents reported that chimneys and entire walls collapsed during the quake.

She said the only food store in town has been shuttered.

The hardscrabble town with 1,500 residents on the edge of a dry lake bed is considered the gateway to Death Valley.
