An earthquake appeared to hit close to San Diego in Southern California on Wednesday morning, but it’s unclear if it was actually a quake. Some speculated that it could have been a sonic boom from a plane. The US Geological Survey hasn’t given an update as to what the incident was.

On Twitter, a large number of people wrote about feeling a quake near San Diego. Some said they felt it in Laguna Beach, Oceanside, and in other parts of Orange County.

The incident appeared to hit at around 9:35 a.m. local time. However, at around 10:15 a.m. and later at around 10:50 a.m., people in Southern California tweeted that they could feel more shaking around San Diego.  “Two times I have felt shaking this morning… earthquake? Or something else?” one person said.

“Just had all of our windows shaking in the house. #earthquake anyone else in #sandiego,” one person tweeted at 10:55 a.m.

The US Geological Survey, which tracks quakes, has not given an update yet about if there was a quake or what the magnitude was.  An earthquake map shows the last quake to hit California was 0.6-magnitude one in The Geysers, located in the northern part of the state. The map didn’t show any recent quakes in Southern California on Wednesday.

However, a large number of people on Twitter were talking about feeling an earthquake.

“Anyone in #sandigo feel some shaking around 9:35? #earthquake #sonicboom,” one person tweeted.
