NELSONVILLE- The U.S. Geological Survey is reporting that a mild earthquake has shaken residents in southeastern Ohio.
The agency says the 3.5-magnitude quake occurred close to 1 p.m. Wednesday. The epicenter was about 2 miles southeast of the town of Nelsonville in Athens County.
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.
Ohio University, in nearby Athens, says its campus felt the earthquake but there was no damage to facilities reported.
Tremors were felt in parts of Wood County.
Some residents in Parkersburg and Waverly reported feeling the quake, though it was felt mainly by those in the upper floors of multi-story buildings.
