After it was reported that an Illinois earthquake rocked the suburbs of Countryside in Cook County, new reports revealed that the alleged Illinois earthquake was, in fact, caused by tremors from a quarry blast Monday. As reported by ABC 7 News, the tremors registered a magnitude 3.2 on seismographs.
The U.S. Geological Survey said the event occurred around noon and the so-called Illinois earthquake only caused minor damage.
"It's not an earthquake," said Don Blakeman, a geophysicist with the U.S. Geological Survey. "We're pretty sure it's a large quarry blast."
According to Blakeman, the organization believes a blast is to blame for the Illinois earthquake scare because there is a limestone close to the area.
Michael Maladonado, who was playing video games during the Illinois earthquake scare, said: "It's freaky. I felt it for maybe four or five seconds. It was like somebody was bouncing on the floor."
"We felt it come as a wave," said Jenylle Rys, who also felt the tremors. "You could definitely feel it on the floor," she said. "I actually thought somebody was in the closet next door doing construction."
