A magnitude 3.8 earthquake occurred in central Indiana on Thursday morning and was felt in several nearby states but with no reports of damage or injuries, government officials said.
The quake occurred at 7:55 a.m. ET with an epicenter about 5 miles southeast of the town of Greentown, geophysicist Randy Baldwin at the National Earthquake Center in Golden, Colorado, said.
The Center had originally reported the quake magnitude as 4.2.
“It was widely felt throughout central Indiana and we have reports of people having felt it over into Illinois, Wisconsin, Kentucky and Ohio,” he said, adding that the quake lasted several seconds. “We haven’t had any reports of any damage.”
Quakes below 5.0 magnitude in the Midwest are generally felt for a range of about 100 miles, officials said.
“There hasn’t been any specific fault at this time that has been attributed to this quake,” Baldwin said.
Judy Oakerson told the Indianapolis Star she felt the quake in her Parker City house.
“I was working at my desk at home and my pup started to whine, just a matter of seconds later the pictures on the wall started to shake and I felt the vibrations on the floor,” she said in an e-mail to the newspaper.
John Strauss, a journalism instructor at Ball State University who lives in Indianapolis, said his 12-year-old Golden Retriever slept through the quake but Strauss felt it as he was working at his computer.
“The house started shaking,” he said. It was over so fast he next thought “Did that happen?”
The first thing Strauss did, he said, was send out a tweet on his Twitter account.
Major earthquakes in the Midwest are rare. But scientists are concerned that the most likely area for a major quake, the region of southeastern Missouri known as the New Madrid Seismic Zone, remains active.
A series of quakes centered there in December, 1811, were felt over an area of 50,000 square miles and rank as largest in U.S. history, according to the U.S. Geological Survey.
