The United State Geological Survey confirmed a sonic boom outside of Hammonton Thursday afternoon that may have caused the earthquake-like shaking across much of South Jersey.


The USGS-reported event originated about two miles north-northeast of Hammonton at 1:24 PM and could be felt as far away as Connecticut.

Immediately following the series of shakes, reports of an earthquake took social media by storm with reports from Cape May to Lakewood all describing the same phenomena. As many as eight separate instances of shaking were reported across South Jersey.

A sonic boom is defined as 'a loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound.'
