A magnitude-4.0 earthquake shook southeastern Michigan Saturday around 12:23 p.m. EDT, a light tremor that was felt as far away as Cleveland, according to the U.S. Geological Survey and CBS Detroit. Earthquakes are rarely experienced east of the Rocky Mountains, according to the USGS, but when they strike, they usually affect larger areas than the more frequent ones in the Western U.S.

The earthquake epicenter was about 9 miles southeast of Kalamazoo, Michigan, and 57 miles southwest of Lansing, the state capital, according to the USGS. Tremors were felt throughout the Midwest, with reports of shaking in Wisconsin, Illinois, Indiana and Ohio, USGS geophysicist Paul Caruso told CBS Detroit. Midwestern residents reported their experiences on Twitter:

A magnitude-4.0 earthquake is “often felt but only causes minor damage,” according to the geology department at Michigan Technological University. Light quakes are defined as those between magnitude 4.0 and magnitude 4.9.
