I was actually out of town, but lots of my friends said they definitely felt this one. Nothing was damaged as far as I can tell.
Via Sign On San Diego:
Once again, a sizable aftershock to the 7.2 Easter Sunday earthquake hits the Ocotillo area. And, once again, it is briefly and lightly felt in parts of San Diego County.
The latest seismic twitch came at 10:21 p.m. Sunday when a 4.2 quake occurred on or around the Laguna Salada fault system, 12 miles southeast of Ocotillo, just over 75 miles east-southeast of San Diego, the U.S. Geological Survey says. The quake began 6.8 miles deep (a common depth for Southern California) and occurred in roughly the same area where 4.9 and 4.8 aftershocks hit on Saturday.
Within 20 minutes of the quake, about 300 people logged into the USGS website to report that they’d felt the aftershock.
The quakes represent a normal aftershock sequence and could occur, on-and-off, for months.
