January 11th, 2011 (San Diego’s East County)—More than 167 people have reported feeling a possible sonic boom at 10:28 a.m., the U.S. Geological Survey reports. The majority of reports came from San Diego and San Diego’s East County, though the incident was felt was far away as Los Angeles County and Tijuana, Mexico.

A loud boom was followed by shaking that rattled windows for 30 seconds or so at East County Magazine’s office in La Mesa. The USGS siet lists the mysterious noise/shaking as a possible sonic boom, but confirms that no earthquake occurred.

Sonic booms have been felt before in San Diego, notably in 2009 and 2006. The 2006 incident was traced to naval training flights 120 miles offshore: .

I hope that there is no going to be earthquake.

this is a shocking news found it only today and it is a bit distressing to read this right now.

I have many relatives in San Diego and I hope that they are alright. The weird thing is that I haven't found this news nowhere in the news.

Thanks for keeping us uptodate.

It wasn't that strong compared to the quakes we've had--

Just enough to get your attention though!  Most likely it was caused by mlitary planes, though there is a theory that booms can sometimes be the result of quakes too small and localized for the USGS equipment to measure.
