This article discusses the use of explosion images to study physical properties, applying the method to the Beirut explosion of August 2020 and estimating the energy yield. The results are consistent with other recent studies using different methods.
Images of an explosion can be used to study some of its physical properties. After reviewing the key aspects of the method originally developed to study the first nuclear detonation and analyzing the Trinity blast data, the method is applied to the Beirut explosion of August 2020 by using images from videos posted online. The applicability of the method is discussed and the process of selection, extraction, and analysis of the data is presented. The estimate for the energy yield of the Beirut explosion is found to be 2.3(-1.1)(+1.1) TJ or 0.6(-0.3)(+0.3) kt of TNT equivalent. The result is consistent with others recently appeared in the literature using different methods. Notice that this article includes content that some readers may find distressing.
