Did you feel it?

<span>The U.S. Geological Survey says there was an earthquake in Southern Illinois on Monday night, just as folks were headed to bed after the 10 o'clock news.</span>

<span>The 2.3 magnitude quake recorded at 10:46 p.m. was centered around Christopher, in Franklin County.</span>

<span>The area is part of the Illinois Basin - Ozark Dome Region, which borders the New Madrid Fault area.</span>

<span>The USGS says minor earthquakes are felt in this region once or twice per year, with a major earthquake happened every 10 to 20 years.</span>

<span>The largest earthquake in the Ozark Dome Region was a 5.4 magnitude quake, which was felt throughout Southern Illinois in 1968.</span>

<span>A 2.3 on the Richter scale is just above the threshold of shaking that the USGS says can be felt by people. Anything below a 2.0 is considered a "micro-earthquake" that is detected by devices but not typically felt by anyone on the surface.</span>
