A earthquake shook Southern California Tuesday afternoon.
The quake hit at 5:38 p.m. and was located about 11 miles east-southeast of Ocotillo and 18 miles west-southwest of El Centro. The United States Geological Survey originally reported that it was a magnitude 5.1 quake but later downgraded that figure to a 4.5.
The region has been on edge since Easter Sunday, when a 7.2 quake rocked the region, doing extensive damage in Mexicali and Calexico. Damage from that quake was even visibile in San Diego, where windows shattered at the Sports Arena and stucco cracked on some buildings. Click here to view the USGS map.
Some felt the quake Tuesday, but, for many, it appeared to be hard to tell.
"Yeah, I thought that was a quake," tweeted gyt. "Didn't think much of it cuz nobody said anything in the office and it was quick."
"Didn't feel it near Mesa College," Sherpa Lurka posted on Facebook.
At least one person seemed unhappy they didn't feel the quake, though.
"Every time I leave town there's a quake," complained Vidalia via Twitter.
One person in North County said she had no doubts about what was happening.
"Up here in Oceanside ... a 'yes,' " Liz Gonzalez-Anchondo posted on NBCSanDiego's Facebook page. "Lots of long swaying. Always look up to my lamp shade to confirm!"
