The Sheriff's Department tells Local 5 they received several calls. They tell us they believe it may be sonic booms making those noises.
The National Weather Service has recorded no earthquake activity in that area.
The boom noises come just months after the Clintonville community felt and heard the aftershocks of a small earthquake.
