Gainesville - Hall County sheriff's deputies have been patrolling the northeast Georgia county after several people reported hearing a mysterious loud noise.

Several residents called 911 to report hearing a loud noise and feeling the ground vibrate between 10 a.m. and 11 a.m. Thursday.

Hall County Maj. Jeff Strickland tells The Times of Gainesville that most reports were from the area of Browns Bridge and McEver Roads.

Lt. Col. James Wilson, a spokesman for Dobbins Air Reserve Base in Marietta, said the cause was probably not an aircraft coming to or from the base. He said its flight schedule does not indicate any aircraft would have been passing through the area then.

Base officials say they've received calls from local law enforcement agencies, and are still looking into the matter.
