M3.8 Earthquake 7:55AM EST Thursday December 30, 2010, in Central Indiana
A small earthquake shook parts of Indiana, Illinois, Michigan, and Ohio at 7:55 a.m. on December 30, 2010.  No reports of damage have been issued thus far.  The earthquake, located about fifty miles north of Indianapolis, Indiana was originally reported to be a 4.2 magnitude, but was later downgraded to a 3.8 magnitude by the U.S. Geological Survey (USGS). According to the USGS, the earthquake has been felt by as many as 6200 people in several states.

This earthquake serves as a reminder of the earthquake risk that exists throughout Indiana.  While the greatest risk for a major earthquake is related to the New Madrid and Wabash Valley seismic zones in Indiana, very few earthquakes are known to have occurred in central Indiana in recent history.  The area is not usually seismically active.
