A loud boom that shook homes in parts of New Jersey early Friday was actually an earthquake.
The U.S. Geological Survey reported that the 2.1 magnitude quake hit near Clementon, Camden County, at 12:13 a.m.
To be precise, the epicenter was near W. Atlantic Avenue and Oak Lane -- a short distance from Clementon Park, according to the USGS.
Residents reported to NBC10 feeling the quake in nearby Pine Hill, Erial and Lindenwold -- some calling and e-mailing the station to say they believe something may have exploded.
There was no explosion though, just the movement of the earth.
There were no immediate reports of injuries or damage from the 3.2-mile deep quake.
