The
T. A. Gillespie Company Shell Loading Plant explosion, sometimes called the
Morgan Munitions Depot explosion or similar titles, began at 7:36 pm EDT on Friday, October 4, 1918, at a World War I ammunition plant in the Morgan area of Sayreville in Middlesex County, New Jersey, United States. The initial explosion, generally believed to be accidental, triggered a fire and subsequent series of explosions that continued for three days, totaling approximately six kilotons, killing about 100 people and injuring hundreds more. The facility, one of the largest in the world at the time, was destroyed along with more than 300 surrounding buildings, forcing the evacuation and reconstruction of Sayreville, South Amboy, and Laurence Harbor (Old Bridge). Over a century later, explosive debris continues to surface regularly across a 1.2-mile (1.9 km) radius.
