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 dctermine the depth and average profile. The results are
summarized in Table 3.1.
