Just when you think things couldn’t get wilder across northern Illinois, a 3.4 magnitude earthquake occurred earlier Monday morning.

This earthquake struck around 2:53 a.m. and was centered to the northwest of the village of Somonauk in extreme DeKalb County.

According to the USGS, it had an estimated depth of 9.8 kilometers. 

Quakes of this magnitude aren’t damage producers, and equates to the energy produced by 1,000 lbs of explosives. Areas across DeKalb County would have likely felt it as well as portions of the western Chicago suburbs from Crystal Lake to Joliet.
