Tianjin explosions On 12 August 2015, at 23:30, two explosions occurred in the Chinese port Tianjin at a warehouse operated by Ruihai Logistics. The more powerful explosion was estimated at 336 tons TNT equivalent. 173 people were killed, and 8 remain missing. 2016 Salawa armoury explosion On 5 June 2016, a fire at the largest military armoury in the island nation of Sri Lanka caused a series of explosions that lasted for about 5 hours. One soldier was killed and several others were injured. 2016 San Pablito Market fireworks explosion On 20 December 2016, a fireworks explosion occurred at the San Pablito Market in the city of Tultepec, north of Mexico City. At least 42 people were killed, and dozens injured. 2020 Tarragona IQOXE plant explosion On 14 January 2020, an ethylene oxide tank exploded at the IQOXE (Chemical Industries of Ethylene Oxide) plant in Tarragona (Spain). 2020 Beirut explosion On 4 August 2020, a warehouse containing of ammonium nitrate exploded following a fire in the Port of Beirut, Lebanon. The explosion generated a pressure wave felt more than away. Following early estimates of the yield of the explosion ranging from hundreds of tons of TNT equivalent to 1.1 kilotons, a study by researchers from the Blast and Impact Research Group at the University of Sheffield estimated the energy of the Beirut explosion to be equivalent to 0.5–1.2 kt of TNT. At least 200 people were killed, more than 6,500 injured, and about 300,000 made homeless. Much of central Beirut was devastated by the blast with property damage estimated at US$10–15 billion. Comparison with large non-nuclear military ordnance The most powerful non-nuclear weapons ever designed are the United States' MOAB (standing for Massive Ordnance Air Blast, also nicknamed Mother Of All Bombs, tested in 2003 and used on April 13, 2017, in Achin District, Afghanistan) and the Russian Father of All Bombs (tested in 2007). The MOAB contains of Composition H6 explosive, which is 1.35 times as powerful as TNT, giving the bomb an approximate yield of 11 t TNT. It would require about 250 MOAB blasts to equal the Halifax explosion (2.9 kt). Conventional explosions for nuclear testing Large conventional explosions have been conducted for nuclear testing purposes. Some of the larger ones are listed below. Other smaller tests include Air Vent I and Flat Top I-III series of 20 tons TNT at Nevada Test Site in 1963–64, Pre
