Rare earthquake rattles northern Illinois

CHICAGO — A small pre-dawn earthquake hit northern Illinois early Wednesday morning, startling sleepy-eyed residents as far away as Iowa and Indiana, but no damage or injuries were immediately reported.

The U.S. Geological Survey reports that the 4.3-magnitude earthquake hit about 50 miles northwest of Chicago at 4 a.m.

USGS geophysicist Amy Vaughan said such quakes are rare in northern Illinois and that the agency received reports from Wisconsin, Iowa and Indiana about feeling the ground shake.

Sheriff’s dispatchers near the epicenter in Kane County said they’ve been flooded with calls from startled residents, but spokesman Lt. Pat Gengler said no injuries or damage have been reported.

Residents reported being tossed out of bed and finding books and tools scattered across the floor.
