A 3.6 magnitude earthquake shook parts of southern Illinois and Indiana Tuesday night.
The quake happened 17 miles underground, just after 5:28 p.m. Central Standard Time, in Wabash County, according to the U.S. Geological Survey.
The epicenter of the earthquake was about 10 miles west-northwest of Mount Caramel, Illinois, or 208 miles southwest of Indianapolis, Ind., the agency said.
That region is part of the New Madrid seismic zone, which sees smaller earthquakes about once or twice a year, the agency said. The largest ever earthquake in the area was a 5.4 magnitude quake, which struck southern Illinois in 1968.
Residents in southern Illinois and Indiana could have felt some weak to light shaking, according to the agency's "ShakeMap."
Preliminary reports did not have information on any possible damage or injuries.
