The explosions were heard over 100 mi (160 km) away, as far as the Netherlands and France, and the resulting flames were visible for many miles around the depot. The explosion occurred at a weekend otherwise the casualties would have been much heavier. A case of butter was found six miles (10 km) away. About 40 tonnes of gunpowder exploded on 12 October 1654, destroying much of the city of Delft in the Netherlands. Wreckage was thrown up to 20 miles (30 km), a collier ship one-half mile (800 m) away had its crane blown off and a crew member killed by a fragment weighing 70 pounds (30 kg). However, the siege continued. At least 51 people were killed, over 100 injured, and twenty buildings flattened. British reports say she was seen to blow up. On 5 April 1958, an underwater mountain at Ripple Rock, British Columbia, Canada was levelled by the explosion of 1,375 tonnes of Nitramex 2H, an ammonium nitrate-based explosive. On 2 July 1918, a munitions factory near Syracuse, New York, exploded after a mixing motor in the main TNT building overheated. [55], On 17 September 1964, the offshore disposal of the ship Village, containing 7,348 short tons (6,666 t) of obsolete munitions, caused unexpected detonations five minutes after sinking off New Jersey. [56], On 28 July 1966, Horace Greeley was loaded with obsolete munitions and detonated off New Jersey at a depth of 4,000 feet (1,200 m).[56]. On 30 January 2007, a Sea Launch Zenit-3SL space rocket exploded on takeoff. Two people were killed and hundreds injured. Arzamas explosion, known also as Arzamas train disaster, occurred on 4 June 1988, when three goods wagons transporting hexogen to Kazakhstan exploded on a railway crossing in Arzamas, Gorky Oblast, Soviet Union.
The explosion consumed the roughly 400,000 kg (400 t) of kerosene and liquid oxygen on board.

[51], On 23 September 1955 in the Mexican city of Gómez Palacio, Durango, two trucks loaded with 15 tons of dynamite exploded when they apparently collided with a passenger train, causing many deaths. Most buildings in a 5-mile radius were rendered flat or uninhabitable. Following the explosion, 258 fellow sailors refused to load ordnance; 50 of these, called the "Port Chicago 50", were convicted of mutiny even though they were willing to carry out any order that did not involve loading ordnance under unsafe conditions.[42]. Eruptions the size of that at Lake Toba 74,000 years ago, at least 2,800 cubic kilometres (670 cu mi), or the Yellowstone eruption 620,000 years ago, around 1,000 cubic kilometres (240 cu mi), occur worldwide every 50,000 to 100,000 years.
Trapped in the crater of their own making; the Union forces were easy targets for the Confederate soldiers once they recovered from the shock of the explosion. The detonations were detected on seismic instruments around the world; the incident encouraged intentional detonation of subsequent disposal operations to determine detectability of underwater nuclear testing.[56]. In the similar Port Chicago disaster (above), about half the weight of bombs was high explosive. Another 9,000 people were injured. This is generally considered the worst industrial accident in United States history. Finally, during the confused night actions in the early hours of 1 June, the German pre-dreadnought SMS Pommern was hit by one, or possibly two, torpedoes from the British destroyer HMS Onslaught, which detonated one of Pommern's 17-centimetre (6.7 in) gun magazines. On December 28, 1944, while transporting ammunition to Mindoro, Philippines, Burke was hit by a Japanese kamikaze aircraft, and disintegrated in a tremendous explosion with the loss of all hands.
