WEST SALEM, Ill. (AP) — Residents across the Midwest were awakened Friday by a magnitude 5.2 earthquake that rattled skyscrapers in Chicago, homes in Cincinnati and nerves across the region but appeared to cause no major injuries or damage.

Dozens of aftershocks followed, one with a magnitude of 4.6.

The quake just before 4:37 a.m. was centered six miles from West Salem, Ill., and 45 miles from Evansville, Ind. It was felt in such distant cities as Milwaukee, Des Moines, Iowa, and Atlanta, nearly 400 miles to the southeast.

"I just saw my house just shake. Golly," said Mike Morrow, of Mount Carmel, Ill., 15 miles southeast of the epicenter, his eyes widening during an aftershock that hit as he was interviewed by a reporter.

Morrow's two-story apartment building was evacuated because of loose and falling bricks.

The quake is believed to have involved the Wabash fault, a northern extension of the New Madrid fault about six miles north of Mount Carmel, Ill., said United States Geological Survey geophysicist Randy Baldwin.
