Mild quake gives many a little thrill. No damage, few injuries reported in Midwest.
By Paul G. Hayes, Journal science reporter.

Because they don't live on the edge of a major continental plate, the people of the Midwest have an advantage over Californians: They can feel milder earthquakes over longer distances. That's the reason the people of Milwaukee and Wisconsin were treated to a harmless little thrill Wednesday evening when they felt tremors from an earthquake centered in bedrock miles beneath Lawrenceville, 300 miles south of Milwaukee in southern Illinois.

The earthquake started at 6:49 p.m. It was felt throughout Illinois and shook tall buildings in Chicago and Springfield. It was felt by people in 16 states from Kansas to South Carolina and in Canada. The quake was a 5 on the Richter scale, meaning that it was capable of causing some moderate damage near its geographical center.

The quake was felt in many Wisconsin buildings, said police from southern to northern Wisconsin, who received telephone calls from people inquiring about mild shaking of homes and buildings. Suburban police departments along the North Shore of Milwaukee received many calls from people reporting that their windows rattled and their furniture moved. Shorewood police said between 30 and 40 people reported the tremors. No one reported damage, police said.
