UPDATE: "Earthquake" Mystery Solved, F22 From Edwards AFB

CENTRAL COAST, Calif- Several people reported feeling a small earthquake shake the area Thursday morning. Calls came in from all over the Central Coast, with people feeling up to 3 "earthquakes". Some people reported hearing a sonic boom.

After this morning event caused a stir, Central Coast News went to track down the answer.

The SLO County Sheriff's Department said, "It's believed the activity was caused by sonic booms from military aircraft flying over this region of California."  The USGS registered two sonic booms at 9:26 AM and again at 9:40 AM, said SLO County. But NORAD told us that there were no missiles that were fired in the area and that Vandenberg was not doing anything that would cause the boom.  

According to the USGS, the only earthquake to hit around 9:34 was a 2.6 centered near Cherry Valley, CA. Click here to see the earthquake details.

However, around 1 p.m. we got this statement from an Edwards AFB Public Affairs Spokesperson, "We can confirm it was an F22 Flying in the Western Pacific Test Range. On an authorize test flight, 50 miles west of the Vandenberg Coast Line. Edwards conducts these types of operations year round. But today's atmospheric conditions allowed the boom to be heard and felt along the Central Coast."
