A small earthquake hit a Chicago suburb Monday night, rattling residents but causing no real damage. The quake, which registered as a 2.4 on the Richter scale, occurred at 9:54 p.m. in McHenry, Ill., 55 miles outside of Chicago.

The epicenter of the quake, which was originally reported to be near Lake Shangrila, was moved by seismologists this morning to Chapel Hill Road, two miles east of McHenry.

It was very minor, USGS geophysicist Jessica Turner told The Chicago Tribune. USGS received some reports of very light shaking in Chicago, 44 miles away, she said.

I was asleep, but my wife was up and heard it, Richard Huemann, who lives on Chapel Hill, told the Chicago Tribune. She said there was definitely a large bang, like an (auto) accident. She looked out, though, and saw nothing.

Some people down the road, however, didn't feel the earthquake at all. I felt nothing, said Arnold Lorenz, who lives on Chapel Hill.

The area was hit with another small earthquake a few weeks ago as well. No injuries were reported in either case, and seismologists said earthquakes of this size are often not even felt.
