The U.S. Geological Survey is reporting that a mild earthquake has shaken residents in southeastern Ohio.
The county's emergency management agency says it received a number of 911 calls about the event but no immediate reports of damage.
Geophysicist John Bellini described the quake as "light." He says people in the area might have felt a quick jolt, while some unstable items could have fallen from desks or shelves.
He says earthquakes must register at a 4.5 magnitude to cause any significant damage.
