A good size aftershock from Friday’s moderate quake rattled a section of the Southland this afternoon. The 4.1 magnitude shaker hit at 2:32 p.m. and was center about one mile southeast of Rowland Heights down in Orange County. In the same area where last night’s 5.1 quake struck, according to the U.S. Geological Survey. It was described as a “… short jolt and then a rolling motion.. “by a resident who felt it.
Dr. Lucy Jones, a seismologist with the USGS, sent out this tweet about the quake.
It’s an aftershock because it is very close to the mainshock. This one is about 3 miles to the northeast. http://t.co/hHZzjnixzr
