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"
Yes. A M4.6 2 mi WSW of El Monte at 11:38. Almost the same location as the M5.9 Whittier Narrows earthquake in 1987

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