Greentown — The U.S. Geological Survey has lowered the estimated magnitude of an earthquake that shook parts of Indiana and four other states to magnitude 3.8.
The agency's initial estimate of the quake's strength was magnitude 4.2. The USGS said the 7:55 a.m. EST Thursday was centered about five miles south of Greentown in Howard County, about 50 miles north of Indianapolis.
The USGS said the quake was felt by people as far away as Illinois, Ohio, Kentucky and Wisconsin. Geophysicist Randy Baldwin said a quake of that magnitude would feel like a loaded truck passing by. No damage was immediately reported, and Baldwin said he didn't expect any.
