The facts are clear: the fear of an earthquake, especially if you live in Los Angeles, is normal. However, an earthquake in Chicago is not as normal. According to a report from ABC affiliate WLS-TV today, the Chicago earthquake that was felt as far north as Kenosha, Wis. was not an actual earthquake, as earlier reports indicated.
Authorities attributed the quake to an explosion in a quarry located in La Grange, Ill. which is near Countryside.
The U.S. Geological Survey confirmed that the alleged "earthquake" occurred at about 12:35: pm Central Time.
"Based on what they've looked at, we're pretty sure it's from a blast," said Paul Caruso, a geophysicist with the U.S. Geological Survey. "It is not an earthquake."
There were no immediate reports of damage or injuries.
While earthquakes are rare in Illinois, the blasting that hit on Monday was strong enough to register 3.7 on seismographs. After further analysis of the alleged earthquake, the Survey concluded that the wave patterns did not match those of a normal earthquake.
A 2.7 magnitude earthquake shook Ewing, Ill. in March of this year, and a previous 3.8 magnitude earthquake rocked the Chicago metropolitan area on the morning of February 11, 2010.
