A strong earthquake that rattled parts of southern Illinois and Indiana early this morning was felt in the Grand Rapids area, about 320 miles away.

The quake, given a preliminary magnitude of 5.4, occurred about 6 miles from Mount Carmel, Ill., and about 131 miles east of St. Louis, according to the U.S. Geological Survey. It took place about 2 miles underground and struck about 5:36 a.m., USGS said.

"It shook our house where it woke me up," said David Behm of Philo, Ill., 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."

The quake also shook skyscrapers in Chicago's Loop and tall buildings in downtown Indianapolis. It was felt in Milwaukee and Cincinnati as well.

Irvetta McMurtry of Cincinnati said she felt the rattling for up to 20 seconds.

"All of a sudden, I was awakened by this rumbling shaking," said McMurtry, 43. "My bed is an older wood frame bed, so the bed started to creak and shake, and it was almost like somebody was taking my mattress and moving it back and forth."

Lucas Griswold, a dispatcher in West Salem, said the Edwards County sheriff's department received reports of minor damage and no injuries.

"Oh, yeah, I felt it. It was interesting," Griswold said. "A lot of shaking."

Indiana State Police spokesman Sgt. Todd Ringle in Evansville, about 38 miles from the epicenter, said there were no immediate reports of damage.

A 5.4 quake can cause considerable damage.

Grand Rapids police dispatchers felt the building shake around 5:30.

Lt. Larry Frye said a couple of dispatchers who work on the fourth floor of Grand Rapids headquarters called him to find out if he felt anything in his lower floor office. He did not notice any tremors.

The USGS received reports from all over West Michigan, including Grand Rapids, Ada, Caledonia, Holland, Wayland and Trufant

The quake occurred in the Illinois basin-Ozark dome region that covers parts of Indiana, Kentucky, Illinois, Missouri, and Arkansas and stretches from Indianapolis and St. Louis to Memphis, according to the USGS.

The organization's Web site said earthquakes occur irregularly in the area, and that the largest historical earthquake in the region -- also a magnitude 5.4 -- caused damage in southern Illinois in 1968.

Three of the most powerful quakes felt in North America struck in the region.

In 1811-12, a series of quakes along the New Madrid Fault in Missouri, near the border with Tennessee, measured 7.8, 8.0 and 8.1, which is 10 times more intense than the 1906 San Francisco earthquake. They devastated the sparsely populated area, and reportedly caused the Mississippi River to flow backward for a time.

The quakes, occurring from from Dec. 16 to Feb. 7, were felt as far away as Boston. Damage was reported as far away as Charleston, S.C., and Washington, D.C.
The earthquake is being monitored by the U.S. Geological Survey.
