GREENTOWN, IN (FOX19) - The U.S. Geological Survey is reporting a magnitude 3.8 earthquake in Central Indiana that was felt in the Tri-State.

The earthquake was reported at 7:55 a.m. with an epicenter five miles from Greentown Ind, which is about 46 miles north of Indianapolis and 150 miles northwest of Cincinnati.

Several residents from all over the Tri-State reported feeling their homes shake.

"I was sitting at my computer and it felt kind of like a little jolt and just like a small little shake to the house," said Randy Baynum, who lives in Covington. "I was looking at my coffee cup and I was watching my coffee kind of swish around back and forth and then my wife came downstairs and I told her, 'We just had a little earthquake.'"

No damage was reported. The quake was felt in Indiana, Illinois, Ohio, Kentucky and Wisconsin.

"It's really quite remarkable how widely this was felt," said John Steinmetz, director of the Indiana Geological Survey in Bloomington.

The quake was originally reported as a 4.2 magnitude, but was downgraded to a 3.8.

Steinmetz said the epicenter of the quake was near the little-known Sharpsville fault, which runs through southeastern Howard and northern Tipton counties. He said quakes were rare in the northern half of Indiana, where only three had been recorded since the early 1800s - one in 1881 and another in 1938.

A earthquake centered in Illinois was felt in the Tri-State on April 18, 2008. Some Tri-Staters also felt a 5.0 earthquake centered in Canada on June 23, 2010.

EARTHQUAKES IN THE STABLE CONTINENTAL REGION
Most of North America east of the Rocky Mountains has infrequent earthquakes. Here and there earthquakes are more numerous, for example in the New Madrid seismic zone centered on southeastern Missouri, in the Charlevoix-Kamouraska seismic zone of eastern Quebec, in New England, in the New York - Philadelphia - Wilmington urban corridor, and elsewhere. However, most of the enormous region from the Rockies to the Atlantic can go years without an earthquake large enough to be felt, and several U.S. states have never reported a damaging earthquake. The earthquakes that do occur strike anywhere at irregular intervals.

Earthquakes east of the Rocky Mountains, although less frequent than in the West, are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast. A magnitude 4.0 eastern U.S. earthquake typically can be felt at many places as far as 100 km (60 mi) from where it occurred, and it infrequently causes damage near its source. A magnitude 5.5 eastern U.S. earthquake usually can be felt as far as 500 km (300 mi) from where it occurred, and sometimes causes damage as far away as 40 km (25 mi).
