Southern California was hit by a powerful earthquake on Thursday around 10:30 a.m. local time, jolting millions across the Southwest who were celebrating Independence Day.
The epicentre of the 6.4 magnitude tremor was near the city of Ridgecrest, which is about 150 miles (240 km) north-east of Los Angeles.
Tremors continued to be felt on Friday, as emergency crews fought fires and provided medical assistance to people.
The quake was felt from Las Vegas in Nevada to Los Angeles on California’s Pacific coast.
It hit at 10:33 local time (18:33GMT) on the US Fourth of July Independence Day holiday.
On Friday morning at 04:15, a tremor measuring 5.4 struck. Los Angeles fire officials said there were no immediate reports of additional damage.
Reacting to the tremor, Ava DuVernay tweeted: “Been living in Los Angeles all my life. That was the longest earthquake I’ve ever experienced. Not jerky. Smooth and rolling. But it was loooong. It was so long I thought for the first time ever “Is this the big one?” Damn. Respect Mother Nature. She’s the boss.”
“I was in my kitchen trying to get some coffee and all the windows started rattling,” said Emma Gallegos, a 34-year-old journalist in southwest Bakersfield. “It was just a little bit at first — I thought something was going by, and then I realized all the windows were rattling. It was kind of a long gentle roll and I felt two distinct waves.”
