LOS ANGELES – No, it wasn’t an earthquake that residents in the Los Angelesarea felt on Friday morning, it was a “sonic boom,” according to Seismologist Dr. Lucy Jones.
“People have been asking about the ‘earthquake’ in LA around 9:20 this morning. Many people report feeling it but the seismograms clearly show the earth was not moving, only the air. So it was a sonic boom,” Jones wrote on Twitter.
