The U.S. Geological Survey initially reported the shaker was a magnitude 5.0, but it was later upgraded to magnitude 5.3.
During a press conference, Dr. Andrews said the off-shore natural disaster is the strongest to hit the area since March 28, 2014, just over four years ago, when La Habra was rocked by a magnitude 5.1 shaker.
Tsunami warnings have not been issued for coastal areas and no major damage or injuries have been reported, according to authorities. It struck about 10.5 miles underground, the USGS said.
"It's a regular sort of natural disaster that we expect somewhere in Southern California", Jones told KTLA.
"Earthquakes are not at all predictable".
Scientists at the California Institute of Technology's seismology laboratory in Pasadena, northeast of Los Angeles, said the natural disaster warning system under development for the West Coast gave about 10 seconds of warning before shaking arrived.
Fire officials in Ventura County, close to the epicenter of the quake, also reported no damage from the shaker.
Some bricks fell from a chimney at an 1860s ranch on Santa Cruz Island but no one was hurt, Yvonne Menard said, spokeswoman for Channel Islands National Park.
It has struck off the coast of LA on the Ring of Fire - a terrifying belt running around the Pacific Ocean where most of the world's quakes take place.
She said that the quake was not strong enough to cause damage on structures.
