Predicting an earthquake or estimating an earthquake's probability is difficult, especially in an area like the central U.S.
Geologists say if an earthquake were to ever hit the city of Cincinnati it would come from the New Madrid Seismic Zone underneath New Madrid, Missouri.
University of Cincinnati Professor of Geology Warren Huff says the zone is about 1,000 feet below the earth's surface.
In 1811 and 1812 the New Madrid Seismic Zone created a series of magnitude 7.0 or greater earthquakes and small earthquakes continue today.
The zone stretches along the Mississippi River and could cause major damage to St. Louis and Memphis.
But Professor Huff says Cincinnati is safe.
"It's not very good, we're in a low probability area because as far as we can tell we don't have any of those major ancient fault zones underneath us," says Huff.
