The U.S. Geological Survey is reporting that a 4.0 magnitude earthquake struck this afternoon in a rural area near Youngstown, Ohio.
The earthquake struck at 3:04 p.m. in an area about five miles northwest of Youngstown and six miles southeast of Warren.
No injuries were reported.
There were no immediate reports of damage. One witness about 20 miles from the epicenter says she saw the ornaments shake on her Christmas tree. Others say it was strong enough to panic pets and send relatives running for cover.
It was the latest in a series of minor quakes in the area in 2011, though residents say Saturday's appeared to be stronger than others. Many have struck near an injection well used to dispose of brine water that's a byproduct of oil and gas drilling.
Its owner agreed this week to stop injecting brine into the earth while the quakes are investigated.
