There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
The RAF Fauld explosion was a military accident which occurred at 11:11 am on Monday, 27 November 1944 at the RAF Fauld underground munitions storage depot in Staffordshire, England. It was one of the largest non-nuclear explosions in history and the largest on UK soil.
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. Over a century later, explosive debris continues to surface regularly across a 1.2-mile (1.9 km) radius.
