On August 4 in Beirut Port, Lebanon, a catastrophic explosion occurred at a warehouse, claiming 204 deaths and injured more than 7000 individuals, with a property loss of approximately US$ 15 billion. An extensive consequence analysis based on the crater size and physical effects for the estimation of the quantity of exploded ammonium nitrate was performed. By using satellite images and integration methods, the crater diameter was determined to be 112.9 m. From the scaling laws, overpressure effect on structures, and inverse analysis, the trinitrotoluene equivalent mass of exploded ammonium nitrate was approximately 950.3 tons. Based on the results of the consequence analysis performed by three methodologies, it can be concluded that the warehouse not only stored a substantially large quantity of ammonium nitrate but was also located too close to the adjacent communities and residential districts without an adequate safety distance. Judging by the simulation results of overpressures and explosive blast on structures, a fatality radius is determined to be about 487 m from the explosion center. Some more lessons related to the time to explosion, phenomena of sympathetic detonation, arrival time of blast, safety distance, fatalities/injuries versus the equivalent mass of trinitrotoluene and a maximum allowable quantity of 30 tons have been learned to be the important guides for safety measures and revisions for limiting the amount of ammonium nitrate under storage.

8月4日，黎巴嫩贝鲁特港一处仓库发生灾难性爆炸，造成204人死亡、7000余人受伤，财产损失约150亿美元。进行了基于陨石坑大小和物理效应的广泛后果分析，以估计爆炸硝酸铵的数量。通过卫星图像和积分方法，确定陨石坑直径为112.9 m。从结垢规律、超压对结构的影响和反演分析，爆炸硝酸铵的三硝基甲苯当量质量约为950.3吨。基于三种方法进行的后果分析的结果，可以得出结论，该仓库不仅储存了大量硝酸铵，而且距离邻近社区和住宅区太近，没有足够的安全距离。从超压和爆炸对结构的模拟结果来看，死亡半径确定为距爆炸中心约487 m。与爆炸时间、共鸣引爆现象、爆炸到达时间、安全距离、死亡/伤害与三硝基甲苯的等效质量和最大允许量30吨相关的更多经验教训已成为安全的重要指南限制储存硝酸铵数量的措施和修订。从超压和爆炸对结构的模拟结果来看，死亡半径确定为距爆炸中心约487 m。与爆炸时间、共鸣引爆现象、爆炸到达时间、安全距离、死亡/伤害与三硝基甲苯的等效质量和最大允许量30吨相关的更多经验教训已成为安全的重要指南限制储存硝酸铵数量的措施和修订。从超压和爆炸对结构的模拟结果来看，死亡半径确定为距爆炸中心约487 m。与爆炸时间、共鸣引爆现象、爆炸到达时间、安全距离、死亡/伤害与三硝基甲苯的等效质量和最大允许量30吨相关的更多经验教训已成为安全的重要指南限制储存硝酸铵数量的措施和修订。
