California Governor Gavin Newsom signed a State of Emergency proclamation hours after the initial quake, according to Ridgecrest Mayor Peggy Breeden.

"Because we've had over 87 aftershocks of this, we don't know what's going to happen and with the State of Emergency, it allows us to seek significant help from other governmental entities," said Breeding.

The 6.4 magnitude quake struck at 10:33 a.m. in the Mojave Desert, about 150 miles (240 kilometers) northeast of Los Angeles, near the town of Ridgecrest, California. It is the strongest quake to hit the region in 20 years.

The United State Geological Survey initially said it measured at a 6.6 magnitude.

Southland police and fire agencies quickly took to social media, reporting no injuries from the shaking, but some possible damage and one structure fire.

Officials said all roadways are passable but continue to make damage assessments.

"I talked just recently to Scott Seymour, the manager at the airport, and there is no damage that he knows of at this time, and they've examined everything out of the airport," said Breeden.

Due to the holiday, the number of personnel working was less than normal, said Ridgecrest Police Chief Jed McLaughlin. However, nearby agencies were able to step in and assist with a grid search of streets to look for damage, downed structures, and any victims, as more resources began coming into the area to ensure public safety was taken care after the dozens of aftershock shook the area.

Battalion Chief Jason Schillinger with the Kern County Fire Department said an Urban Search and Rescue task force with the Office of Emergency Services will be in the area assisting local agencies with K-9 dogs.
