5.4 Earthquake Rocks Illinois;

WEST SALEM, Ill — A 5.4 earthquake early Friday rocked people awake as far away as Indiana, surprising residents unaccustomed to such a large Midwest temblor.

The quake just before 4:37 a.m. was centered 6 miles from West Salem, Ill., and 66 miles from Evansville, Ind. There were no immediate reports of injuries.

"It shook our house where it woke me up," said David Behm of Philo, 10 miles south of Champaign. "Windows were rattling, and you could hear it. The house was shaking inches. For people in central Illinois, this is a big deal. It's not like California."
