LOS ANGELES, California (CNN) -- A magnitude-5.8 earthquake has struck just east of Los Angeles, according to the U.S. Geological Survey.

The quake's epicenter was about 2 miles southwest of Chino Hills and about 5 miles southeast of Diamond Bar, the USGS said. Chino Hills is about 30 miles east of downtown Los Angeles.

The center was about 7.6 miles deep. In general, earthquakes centered closer to the Earth's surface produce stronger shaking and can cause more damage than those further underground.

A 5.8 magnitude quake is considered by the USGS to be "moderate," which can cause slight damage to buildings and others structures. About 500 can happen globally each year, the survey says.

"I can tell you that we had a good-sized shake here in the bureau," said CNN Los Angeles Bureau Chief Pete Janos. "It started slowly. It continued on, shaking the bureau pretty well. ... Right now we're just sort of assessing the situation. Nothing fell off the walls ... but there definitely was a shake."

Janos said he has lived in southern California for about 12 years, and "I can tell you this is probably the best one we have had."

He said the quake "picked up steam. At its height, the building was doing some good swaying back and forth." He estimated the quake lasted no longer than about 20 seconds.

"We could definitely feel it on the third floor," said Kara Finnstrom, who was in Hollywood. "That feeling where you scramble to get under something because you know it's large enough -- you wonder what's going to happen next."

CNN's Ed Lavandera was at Disneyland in Anaheim, southeast of Los Angeles, with his family and felt the temblor. He said the shaking lasted about 5 seconds.

CNN affiliate KABC is reporting that Disneyland's rides have been evacuated.

Lavandera was standing in line for a ride when he saw the ride's top "shaking back and forth." "

You could hear the metal kind of clanging around, and the ride was just ending, so for a moment ... I thought maybe something was wrong with the ride. Then I realized the ride had already stopped moving and the ground was still moving," he said.

There were no immediate reports of injury or damage in Los Angeles, Los Angeles Fire Department spokesman Brian Humphrey told The Associated Press. San Bernardino County fire dispatch did not have reports of damage, AP said.
