4.5 aftershock reported in Midwest
WEST SALEM, Ill. (AP) - April 21, 2008 Geologists say the temblor just before 12:40 a.m. registered 4.5
magnitude at its epicenter about 5 miles northwest of Mount Carmel.
The location is in the same area as Friday's early morning
earthquake, which shook a wide area of the Midwest and caused minor
damage.
The Monday morning aftershock was the 18th since Friday and the
second strongest, according to the U.S. Geological Survey. The
strongest was a 4.6 magnitude shaker about 5½ hours after the
original quake Friday morning.
