estimates of areas at risk of high damage and casualties, and will provide
policy makers and the public with more accurate information about the event. On
4 August 2020, an explosion occurred in the Port of Beirut, Lebanon. Shortly

Experimental measurements of shock wave propagation from explosions of C4 are
presented. Each test is recorded with a high-speed digital video camera and the
shock wave is visualized using background-oriented schlieren (BOS). Two
different processing techniques for BOS analysis are presented: image
subtraction and image correlation. The image subtraction technique is found to
provide higher resolu... hiện toàn bộ
