Earthquake shakes Indiana

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 are reporting that they felt their homes shake.

So far, there is no report of damage. The quake was felt in Indiana, Illinois, Ohio, Kentucky and Wisconsin.

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

USGS geophysicist Randy Baldwin said there are no known fault lines in that area. But he said quakes can occur "pretty much anywhere" and a magnitude 4.2 quake would feel like a loaded truck rumbling by.

Here are the details on Thursday's earthquake from USGS:

Event ID


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).
