Chicagoland Earthquake?

blog_breaking1earthquakeAt exactly 1pm, seismic sensors southwest of Chicago┬áregistered a 2.7 magnitude temblor. While a reading of 2.7 is considered very weak, the location of this shaking is a bit suspect. As pictured here, the epicenter of this event is very near a large quarry in the city of LaGrange. Although several people reported the shaking, it only lasted a couple of seconds. Most earthquakes shake the ground for much longer than this, which suggests that this may have been a man-made incident. If this afternoon’s shaking was in fact caused by quarry blasting, the amount of explosives used must have been enormous to register a 2.7 magnitude quake! Did you feel anything or know anyone that did?119

    A friend in Cortland felt it. Id be surprised if a quarry blast really made it that far.

    That is very interesting. It may in fact have been seismic activity. The low magnitude, location, and time of exactly 1:00pm had originally lead to skepticism about the origin of this shaking, but as reports keep coming in, it may in fact have come from mother nature.

    Have there been any reports or has anyone investigated to see if there was a blast at the quarry at 1pm? Because I would think if there was a recorded blast at 1pm, then that could determine if it was an earthquake.

    Q: What’s the easiest way to find the earthquake faults in California?

    A: Just look where the nuclear power plants are built.
