19. ABSTRACT (Continue on reverse if necessary and identify by block number)
The purpose of this report was to study the general characteristics of the craters
formed from nuclear explosions in connection with Operation Greenhouse to formulate general
rules as to their size and shape.
On the basis of the results, it was concluded that (1) craters on Eniwetok Atoll may be
roughly described as conical sections and scaling relationships for the depth, radius, and
volume are given as functions of yield; (2) crater formations are significantly affected not
only by local soils but probably by the major geological structure of the Atoll; and (3) the
completely different phenomenology involved in nuclear explosions in comparison with TNT
denies any justification for attempting to scale to correlate the results of TNT with
nuclear explosfons short of the detailed considerations of the very different early hydrodynamic history of each explosion.
