Abstract : The objective of this project was to measure the physical characteristics of craters produced by the detonation of nuclear devices so as to obtain a more thorough understanding of crater-prediction phenomenology. Crater measurements were made on the five surface or near-surface shots: Lacrosse, Zuni, Seminole, Mohawk, and Tewa. Crater radius, crater depth, and approximate profile were determined by use of aerial photography and lead-line sounding techniques. Aerial mapping photographs were made of the craters after the shots, and these were used to plot ground elevations to give the crater radius. Lead-line soundings were made along diameter(s) of each crater to determine the depth and average profile. (Author)
