Boulders Plummet Onto California Highway After 6.0 Magnitude Earthquake

Videos and photographs posted across social media captured boulders plummeting onto a California highway after the state experienced a 6.0 magnitude earthquake.

In one video posted to Twitter by user Brett Durrant, numerous boulders are scattered across Route 395. Cars can be seen swerving around the boulders in the road, while one man attempts to move the rocks out of the way.

"We had to get out and move boulders to clear the roads and all I was thinking was that if there is an aftershock we are in big trouble. The hills above us felt very ominous," Durrant wrote in a subsequent tweet.

Another video, posted to Twitter by KGET-TV, captured the moment the boulders began falling from mountains adjacent to the highway.

"Viewer videos from our Bay Area affiliates show boulders coming down in Coleville following the 5.9 magnitude earthquake in Northern California," KGET said in the tweet.

The Caltrans District 9 Twitter account posted several other pictures of boulders on California roads following the earthquake. Caltrans is the California Department of Transportation.

"A string of earthquakes sent rocks tumbling onto U.S. 395 yesterday afternoon. Crews from our Sonora Junction Maintenance Yard responded quickly to remove the boulders and escort vehicles out of Walker Canyon," the tweet said.

On Thursday, the U.S. Geological Survey reported that the earthquake hit parts of Antelope Valley near California's border with Nevada. The quake "occurred as the result of normal faulting in the shallow crust of the North America plate," the USGS said. "This earthquake occurred along the eastern edge of the Sierra Nevada, a major physiographic boundary along the California-Nevada border."

According to the USGS, at least 33 other earthquakes, with a 5.0 magnitude or higher, have occurred within 100 kilometers of Thursday's quake in the past 100 years.

"The largest of these were a M6.1 earthquake 36 km to the northwest in September 1994 and a M6.1 earthquake 63 km to the north in June 1933," the USGS said.

The Associated Press reported that aftershocks from the earthquake were felt as far away as San Francisco and Las Vegas.

Brian Ferguson, a spokesman for the California Governor's Office of Emergency Services, told the AP minor road damage was reported and but no severe impacts to buildings.

"We were relieved it wasn't anything more substantial," Ferguson said.
