Ball State University employees determined the campus sustained no damage from Friday's 5.2 magnitued earthquake, a university official said.
Layne Cameron, media relations manager, said the quake was treated as a training exercise, as if significant damage could have been done. Employees did thorough checks of campus buildings, including tunnels, towers and swimming pools, Cameron said.
The earthquake's epicenter was six miles from West Salem, Ill., about 180 miles from Muncie, and occurred at 5:37 a.m.
After the quake, Indiana Department of Transportation crews inspected bridges and highway overpasses.
The earthquake was part of the Wabash Valley fault, a northern extension of the New Madrid fault about six miles north of Mount Carmel, Ill.
Larry Braile, head of Purdue University's Department of Earth and Atmospheric Sciences, said Friday's quake was the most powerful in the Midwest since a magnitude 5.5 rocked southeastern Illinois in November 1968.
Phil Roberts, an earthquake consultant for Indiana, said the state experiences hundreds of earthquakes each year with magnitudes ranging from 1.2 to about 2.0 - too weak to be felt.
