Magnitude 3.6 Earthquake Shakes Northern Illinois, Felt Across State Lines

No damage reported from the early morning quake centered near Standard, Illinois, felt as far as Wisconsin, Iowa, and Indiana.

A magnitude 3.6 earthquake rattled northern Illinois and parts of three other states early Wednesday, awakening some residents and spurring reports to 911 about homes shaking, the U.S. Geological Survey and police said.
The small earthquake was detected about 4:41 a.m. local time and was centered about sixth-tenths of a mile south-southeast of Standard, Illinois, a town that's about 100 miles southwest of downtown Chicago.
People living as far away as southern Wisconsin, southeastern Iowa and northwest Indiana reported that they felt the quake.
While there’s neither a history of large quakes in that area of Illinois, nor a known fault zone in that region, small to moderate earthquakes can occur anywhere and anytime in the Eastern U.S.
There were no reports of damage due to the earthquake.
