GREENTOWN, IN (WFIE) - A 3.8 magnitude earthquake rattled residents in north central Indiana Thursday morning.
The US Geological Survey confirmed that the quake struck just before 7 a.m. Evansville time, five miles southeast of Greentown (46 miles NNE of Indianapolis).
"(It) sounded like a jet engine roaring past our house!," wrote one Westfield resident on Twitter.
The quake was felt as far away as western Ohio.
The USGS preliminary report pegged the magnitude at 4.2 before adjusting it about an hour later.
Some residents described items rattling on shelves.
There are no reports of any injuries or significant damage from the mild quake, which took place while many residents were still asleep.
Howard County Chief Sheriff's Deputy Steve Rogers says the department was bombarded by phone calls after the quake from people wondering what had happened. He says some people reported hearing a loud boom.
Indiana University geologist Michael Hamburger told Indianapolis television station WTHR the temblor occurred in an area "that's seismically very quiet."
