An earthquake struck east of downtown Los Angeles at 11:38 p.m. According to the U.S. Geological Survey the quake hit about 2 miles southwest of South El Monte and had a preliminary magnitude of 4.5.

Initial reports have the earthquake's magnititude, which has since been revised downward twice which is not uncommon as scientists assess the data coming in from their monitors.

Seismologist Lucy Jones reported from Pasadana via Twitter:

"Still getting everything processed, but it was a pretty good jolt here in Pasadena"

As Jones noted in her Tweet, it's the same location of the deadly 1989 Whittier Narrows quake. That temblor killed eight people and caused $360 million in damage.

The USGS is asking for people if they felt the quake, information they use to determine the range of the shaking.
