On Aug. 4 , a series of monolithic explosion sway the interface of Beirut in Lebanon , and the biggest was one of the most sinewy blasts in chronicle that was not produced bya nuclear bomb , consort to a newfangled analytic thinking .
Never before had such a large explosion been so well - document . Many witness immortalize the here and now of the detonation and the subsequent blast wave on picture , sharing the terrifying scenes on societal spiritualist .
Preliminary yield estimation of the 2020 Beirut explosion using video footage from social media. Numbers indicate filming locations of the 16 videos used to estimate the yield of the 2020 Beirut explosion. Satellite imagery from Google Earth (Jan. 2020).
Recently , railroad engineer at the University of Sheffield in the United Kingdom analyzed 16 such videos that were captured from different locations around the plosion and had an unobstructed persuasion of the event and its consequence . From this visual evidence , the researchers were then able to figure the strength of the blowup , they reported in a new study .

The researchers collected 38 information points from the telecasting , nail the reaching of the blast undulation based on audio pool stick , frame - by - frame video analysis , and the size of it of the explosion ’s fireball .
The engineers found that the cataclysm was equivalent to the detonation of 550 to 1,200 tons ( 500 to 1,100 metrical tons ) of the explosive chemical substance chemical compound trinitrotoluene ( TNT ) — about 5 % the strong point of the nuclear turkey that the U.S. degenerate onHiroshimaon Aug. 6 , 1945 . In a issue of milliseconds , the Beirut detonation bring out approximately 1 gigawatt hour ( GWh ) of free energy , or as much energy as is produce in one minute by more than 3 millionsolar panels ; 412 wind turbine ; or 110 millionLEDs , according to theU.S. Department of Energy .
That ’s enough exponent to bring home the bacon electrical energy to over 100 home for about a class , university representativessaid in a affirmation .
The blasts , which killed at least 180 people and injure more than 6,000 , were due to a fire that ignited a 2,750 - long ton ( 2,500 - metric - ton ) reserve of highly volatile ammonium nitrate that had been stored at the embrasure , Live Science previously reported . A massive mushroom swarm that rose from the wreckage — made up of toxic atomic number 7 dioxide gas — organise after the solid ammonium ion nitrate decomposed into natural gas and water vapor .
The plosion damaged about half the buildings in Beirut , fire more than 250,000 people ; and silo hold 85 % of the country ’s wheat stores were either destroyed or were so badly damaged that the grain was no longer comestible , The New York Times reportedon Aug. 7 .

" After seeing the events unfold , we wanted to use our expertness in blast engineering to aid understand what had fall out in Beirut and offer data point that could be used to help groom for , and save life in such events should they ever happen again , " lead study source Sam Rigby , a aged lecturer in Blast and Impact Engineering at the University of Sheffield , aver in the statement .
" By read more about the power of magnanimous - shell inadvertent explosions like the one that occurred in Beirut , we can evolve more exact predictions of how unlike buildings will be sham , and the types of injuries there are potential to be at different length from the blast , " Rigby say .
The determination were published online Sept. 22 in the journalShock Waves .
