I created this page to save and track mystery San Diego, CA area earthquakes that are supposedly "not earthquakes" but have gone completely unexplained. I have personally felt each of these. Each felt about a 3 on the Richter scale.
Starting to get skeptical!

UPDATE: May 22, 9:45 a.m.: Military officials told 10News they are unaware of anything on base that may have caused widespread shaking.

SAN DIEGO (KGTV) - San Diego County residents reported notable shaking Tuesday evening, but a U.S. Geological Survey seismologist said it was not due to an earthquake.

The City of Coronado tweeted the shaking was felt in council chambers about 5 p.m.

10News also received calls and messages from residents in Chula Vista and Imperial Beach who thought they had experienced an earthquake.

However, employees at the Sunglass Hut and Panera Bread on Orange Avenue said they did not feel shaking.

A USGS expert confirmed to 10News our region did not experience an earthquake around 5 p.m. The most recent quake nearby was in Baja California Tuesday morning.

10News has reached out to Coronado authorities and the U.S. military in an effort to determine possible causes of the shaking.

SAN DIEGO (KGTV) - A number of San Diego residents have reported to 10News that they felt a "boom" Thursday morning.

Some San Diegans said the unexplained sound/movement occurred just before 11 a.m.

The U.S. Geological Survey did not report an earthquake in the immediate area. A 2.8-magnitude quake was reported at the Northern California-Nevada border at around the same time, the USGS website indicated.

Yeah, what the heck was that? My windows rattled like crazy, but did not feel the ground moving.

Felt in La Mesa where I seldom ever feel them. Very odd vibration like a truck going by but I did feel the ground move and saw patio awning cords swing back and forth.

Sherman Simbulan, who lives in the Webster area, felt it while working on a car outside.

"It was pretty strange. First I heard what sounded like a low, distant boom, and then I felt the rumble. And it was very, I would say gradual, as it came to me," said Simbulan. "Instantly thought earthquake, but froze for a second, looked around, nothing is shaking, nothing swaying, my cup did not fall over."

Others felt it in Chula Vista, Encanto, Coronado, La Mesa, Valencia Park, El Cajon, Lakeside, Lemon Grove and National City.

10News reached out to Camp Pendleton, MCAS Miramar and the Navy. Each say no exercises conducted on Monday were the cause of the boom.

10News is working to find out more about the tremor and will update this story when more information becomes available.
