2.4 magnitude quake shakes Wisconsin-Illinois border

MCHENRY, IL --  A small earthquake was reported near the Wisconsin-Illinois border around 9:54 p.m. Monday. According to the U.S. Geological Survey (USGS) the minor 2.4 magnitude earthquake shook McHenry County,  Illinois.

The USGS initially reported the epicenter of the earthquake in the town of Bristol, Wisconsin. The USGS now says the epicenter was on Chapel Hill Rd., two miles east of McHenry, IL.

A 2.4 magnitude earthquake has a low impact. According to the USGS, any earthquake below a 3 on the Richter Scale is not serious, and sometimes these earthquakes are not even felt. There have been reports of tremors being felt as far down as the Chicago suburbs as a result of Monday's quake.

In McHenry, Illinois Monday, a gas station attendant says the minor earthquake was a major topic of discussion! Some say they felt nothing, while others report they did notice the quake Monday night. "I was watching TV, and all of a sudden I heard 'boom!' It scared me," Megan said, outside of Steak 'N Shake in McHenry Tuesday.

In Twin Lakes, Wisconsin, Katie Mathia says she couldn't understand why her dog, Hunter, because so clingy Monday night. "He just wasn't himself. He was real uneasy and just didn't want to leave me. He just wanted to stay by me and make sure that I was okay, for some reason," Mathia said. She says she didn't know about the earthquake until her boyfriend got home and told her about it, about a half-hour after the quake.

McHenry police say with this quake being the second in two years, first responders may have to include earthquakes into their emergency preparedness plans.
