Determining the power of explosions is difficult, but this was probably the largest planned explosion in history until the 1945 Trinity atomic weapon test, and the largest non-nuclear planned explosion until the 1947 British Heligoland detonation (below). The Messines mines detonation killed more people than any other non-nuclear deliberate ...
It was the deadliest industrial accident in U.S. history and one of history's largest non-nuclear explosions. The explosion was triggered by a mid-morning fire on board the French-registered vessel SS Grandcamp (docked at port), which detonated her cargo of about 2,300 tons (about 2,100 metric tons) of ammonium nitrate.

While hundreds of detonations were spread over three days, the totality of the event ranked as one of the largest man-made non-nuclear explosions in history. Some of the strongest individual blasts, from exploding storehouses or railcars of ammunition, broke windows as far away as Manhattan and Asbury Park , more than 20 miles (32 km) distant.
STORY: The blast on Aug 4, 2020 killed at least 220 people. One of the largest non-nuclear explosions in history, it was caused by massive stores of ammonium nitrate kept at the site and neglected ...
RAF Fauld explosion – An underground Royal Air Force ordnance depot exploded, causing the United Kingdom's largest ever explosion. 9 May 1945 United States: Sunnyside, Utah: 23 Unknown Gas explosion at the Sunnyside Fuel Company's #1 mine. 25 May 1945 United States: Aberdeen, Maryland: 12 ~50 1945 Edgewood Arsenal explosion: 21 May 1945 Australia
In the 1950s and early 1960s, the explosions sent mushroom clouds high into the skies above the New Mexico and Nevada deserts. Testing later was limited to underground explosions, which ended in 1992.
The fatal explosion involved at most a few tonnes of explosive. A larger explosion of about 80 tonnes of ammonium nitrate emulsion, ANE, an emulsion of ammonium nitrate, fuel and water, UN 3375) was caused by fires under storage facilities at the site at 11:02 AM. There were no fatalities in the second explosion because the site had been evacuated.
On this day in 1957, the first underground nuclear test was carried out at the Nevada Test Site, a 1,375 square-mile research center located 65 miles away from Las Vegas.The 1,7 kiloton nuclear ...
