Update March 26, 2015 – 630am CDT:
Last nights odd earthquake in Chicago… reports from the event coming in.. people reported hearing a “thunderous sound” accompanying the rare seismic event.
“The U.S. Geological Survey reported a quake of magnitude 2.9 hit about 1-1/4 miles west of Lake in the Hills at 6:08 p.m. USGS data show that if confirmed, it would be the biggest seismic event in the Chicago area since one near a McCook quarry on Nov. 4, 2013, measuring 3.2. Before that, the largest in recent years was Feb. 10, 2010, when a 3.8 quake hit near Elgin.
East Dundee resident Julie Loewe said she was watching television in her room when she heard “a thunderous sound.”
“My son ran into my room saying, ‘Was that an earthquake?’ and I said, ‘I think so.’ My walls were shaking,” Loewe said.
She said she was one of the first of her friends to post on Facebook that she thought an earthquake had occurred.
“And then it was confirmed,” she said.”
