Preliminary data suggests Friday night’s earthquake occurred on the Puente Hills thrust fault, which stretches from the San Gabriel Valley to downtown Los Angeles and caused the 1987 Whittier Narrows earthquake.
Friday night’s 5.1 earthquake hit only about 2 to 3 miles beneath the surface, which means the shaking is very concentrated in a small area, officials said.
So far, there have been reports of only moderate damage from the quake. Residents in La Habra, near the epicenter, have sent out pictures on social media showing broken vases, topped furniture and items scattered around their homes. No structural damage has been reported so far.
Disneyland has closed some rides, according to guests. Some said they were stuck on rides.
The Los Angeles Fire Department said there have been no reports of significant damage in Los Angeles. Power was out in some neighborhoods near the epicenter. There are no reported injures.

The 5.1 magnitude earthquake that rattled Southern California Friday night raises the possibility that a larger quake is on the way, seismologists said. (It was originally listed as 5.3 magnitude).
The swarm of earthquakes began at 8:03 p.m., when a 3.6 earthquake hit. That ended up being a foreshock of the largest earthquake to hit, a magnitude 5.1 at 9:09 p.m. At least two more aftershocks hit in the 3 range — a 3.4 at 9:11 p.m. and a 3.6 at 9:30 p.m.
U.S. Geological Survey seismologist Lucy Jones said the 5.1 quake has a 5% chance of being a foreshock of an even larger quake.
“There could be even a larger earthquake in the next few hours or the next few days,” Jones said at Caltech.
In Orange, a few miles to the east of the epicenter, patrons at BJs Brewery went from boisterous conversation to tense silence. The suspended LED lights swayed. When it was over, the room erupted in applause.
Residents in Orange County reported the quake lasted for about 10 seconds. They said they felt gradual shaking.
The quake was felt across a large swath of Southern California. The Los Angeles Fire Department said it is going into emergency mode and looking for signs of damage or injuries.
According to the USGS, the epicenter was one mile from Brea, three miles from Rowland Heights and three miles from Fullerton.
