The supervisor of Pembroke Township of Kankakee County in northeastern Illinois says an April earthquake may be the cause of a massive water main break. Larry Gibbs says officials found the leak in an area "out in a field with no disturbance around it." He says the leak is responsible for the loss of hundreds of thousands of gallons of water. A series of earthquakes, one as strong as 5.4, rocked Illinoisans starting April 18th. It was felt as far away as Ohio and Kentucky and in Chicago's Loop, 240 miles north of the epicenter in West Salem. Gibbs says local officials speculate the earthquake is the cause of the leak. He says workers are trying to fix the break.
