Illinois quick hits: Earthquake shakes Illinois; researchers look into cicada damage; sinkhole grows in Alton

Earthquake shakes northern Illinois

Parts of northern Illinois shook Monday as a 3.4 magnitude earthquake struck in the early morning hours. The earthquake was centered northwest of the DeKalb County village of Somonauk. According to the United States Geological Survey, the trembler had an estimated depth of about 6 miles. The earthquake could be felt as far as Joliet.

Researchers look into cicada damage

With a rare, double emergence of cicada broods in Illinois completed, researchers are now looking at the damage caused by the phenomenon. Researchers at the University of Illinois Department of Crop Sciences are requesting that fruit growers report any sustained damage done to trees, bushes or vines. The most visible damage would be slits on small branches. Researchers say the slits would weaken a branch to the point that it would snap off during windy conditions.

Sinkhole in Alton getting worse

A massive sinkhole that swallowed part of a soccer field in Alton continues to grow. The field at Gordon Moore Park was partially swallowed up two weeks ago. The park has since been closed, but officials said the problem appears to be getting worse. The city received approval from the Mine Health and Safety Administration to drill under the park access road to help determine what actions need to be taken.
