Earthquake hits Ottawa
Many in Midwest feel the tremble
OTTAWA -- A brief earthquake struck the Midwest early Monday, rattling windows and awakening sleeping residents from
Wisconsin south to Missouri and from southwestern Michigan west
to Iowa.
No injuries were reported from the quake, which occurred
about 1:11 a.m.
Brian Lassige, a geophysicist with the U.S. Geological Survey in Colorado, said the quake was magnitude 4.5, and its epicenter was about eight miles northwest of Ottawa in northern Illinois, close to the small village of Troy Grove. The rural area is about 80 miles south of Rockford.
Lassige said earthquakes in that area are rare but have occurred before. He said quakes have been recorded there in 1881, 1912 and 1972.
The geological survey said the three-second quake occurred at a depth of 3.1 miles in a structure associated with the Sandwich Fault Zone. It was not connected with the New Madrid Fault further south, which has been responsible for the Midwest's most serious earthquakes.
Initial reports indicated no major damage from the temblor, although police agencies and radio stations within the quake area were inundated with telephone calls.
The quake was felt at three nuclear power plants in Illinois: Quad Cities, LaSalle and Dresden.
