A moderately strong earthquake that rattled central California on Wednesday triggered a rock slide that sent boulders and debris crashing into a camping area.

The United States Geological Survey (USGS) said the quake had a preliminary magnitude of 6.0 before downgrading it to 5.8. The temblor jolted the area around 10:40 a.m. and had an epicenter of about 10 miles south-southeast of Lone Pine, Calif.

Lone Pine is located between Sequoia National Park and Death Valley National Park.

Clouds of dust could be seen hanging in the air close to the parking lot and camping ground in a video posted to Twitter by John Chrissinger.

WARNING: GRAPHIC LANGUAGE

Chrissinger told Storyful he was standing in the picnic area at Whitney Portal when he heard a "low rumble" and then "a few pretty hard shakes to the right and left" that lasted about 10 seconds.

“There was a thunderous crash and you could see part of the mountain coming down, lucky that we were on the other side of the portal road, I did not have time to video the landslide it all happened so fast, was over in 30 seconds," he told Storyful. "Funny it was just dead silence and all the dirt rising up after the slide. Felt really eerie."

Another photo he took showed a large boulder that "took out several campsites and trees."

Other videos also showed dust clouds on area mountains after the quake.
