The Los Angeles Police Department said it has not yet received any reports of damage or calls for service within the city, but officials urged people to only call 911 in an emergency out of fear the call lines could get clogged.

"We are aware of the significant earthquake that just occurred in SoCal PLEASE do NOT call 9-1-1 unless there are injuries or other dangerous questions Please do not call for questions," the Los Angeles Fire Department tweeted.

The quake is the largest to hit Southern California since the 6.6 magnitude Northridge quake in 1994, which killed dozens and caused billions of dollars in damage. However, while that quake hit the center of a populated area, Thursday's epicenter was more removed from metropolitan Los Angeles.

People reported feeling tremors from the Mojave desert to the Pacific Coast.

"I was in my kitchen trying to get some coffee and all the windows started rattling," Emma Gallegos, a 34-year-old journalist in southwest Bakersfield, told the Los Angeles Times. "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."

“I was laying down in my bed and I had my feet on the wall and I felt like both of the sides of the house were moving and shaking so I ran, and grabbed my brother and kid and came outside,” said Edith Mata, 22, a student at Bakersfield College.

The quake was felt in the Los Angeles area for about 30 seconds, according to local reports.
