No serious damage or injuries reported after 6.4 magnitude earthquake, the most powerful to strike region since 1994
The largest earthquake to hit southern California in decades rumbled across the region on Thursday morning, striking a remote part of the state with a magnitude of 6.4 on the Richter scale.
The earthquakes center was near the small city of Ridgecrest, near Death Valley national park and about 100 miles (160km) from Los Angeles. There were reports of people in Las Vegas and Los Angeles feeling the tremors.
There were no immediate reports of serious damage or injuries after the earthquake struck at 10.33am. A series of small aftershocks followed.
It was the most powerful earthquake to strike the region since 1994, when the 6.7 magnitude Northridge earthquake hit the populated San Fernando Valley. The Northridge earthquake caused 57 deaths and billions in dollars of damages from collapsed buildings and destroyed freeways.
One of the worlds foremost seismologists, Lucy Jones, told reporters that CalTechs seismology lab received a warning about 48 seconds before the shaking started.
Jones warned much larger aftershocks should be expected within the next 24 hours.
The director Ava DuVernay, shared her Los Angeles-born grandmothers unflustered response to the quake on Twitter:
While others joked about the small impact the earthquake had in major Californian cities:
John Vidale, professor of seismology at the University of Southern California (USC), said if the earthquake had hit the city of LA, there could have been major consequences.
Its a big enough earthquake to cause considerable damage, he told the Guardian, comparing it to the 6.3-magnitude earthquake in the city of Christchurch in New Zealand, which flattened parts of the city in 2011 and killed 185 people. If this had hit in Los Angeles, there would probably be a five or 10-mile area that was badly damaged. Weve come along way since the 1970s, but there are still a lot of vulnerable structures out there.
The fire department in Kern county said the Ridgecrest regional hospital was undergoing evacuations, but the extent of the damage was unclear. Fire officials in nearby San Bernardino county said there were multiple buildings with minor cracks, broken water mains, power lines down and rock slides, but that there were no injuries or fires reported.
Even though the earthquake was outside of the city of LA, it could serve as a wake-up call for people to make sure they are prepared, Vidale said: Itll help put people in the right frame of mind.
Vidale said he was also surprised at how strongly he felt the quake at USC in LA: At first I felt the swaying, then I felt a pretty distinct rattling, and could see the blinds moving back and forth. I didnt know if it was going to turn into something more violent.
