Chicago, IL (AHN) - Several aftershocks have been registered following a 5.2 magnitude earthquake that shook the Midwest early Friday morning.

One of the aftershocks was quite strong, at 4.6 on the Richter scale, according to U.S. Geological Survey geophysicist Angel Gutierrez. It occurred 10:15 a.m. The number of aftershocks observed ranged from 6 to 12, with lesser magnitudes ranging from 2.2 to 2.5.

The first tremor, 5.2 on the Richter scale, hit the Midwest at 4:36 a.m., near West Salem town, 60 miles northwest of Evansville in Indiana.

Even with the aftershocks, there were still no reports of any injuries or damage caused by the dawn temblor, except for a crack on U.S. Route 51 near Cairo, according to Mike Claffey, a spokesman for Illinois' Department of Transportation. State crew are going around major thoroughfares checking roads and bridges for earthquake-related damage.

The last tremor that rocked the Midwest with a similar strength was a 5.0 earthquake in 2002.
