Chapter 4 Conclusions and Recommendations 4.1 CONCLUSIONS On the basis of previous results and discussions, it is concluded that 1. Craters on Eniwetok Atoll may be roughly described as conical sections with depth, radius, and volume given approximately by the equations in Sec, 3.2, 2. Crater formations at Eniwetok Atoll are significantly affected not only by local soil characteristics but probably by the major geo- logical structure of the Atoll. 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 explosions short of the detailed considerations of the very different early hydrodynamic history of each explosion. 4, From the relatively small size of the alleviate the danger by detonation on a barge in the lagoon. 4.2 RECOMMENDATIONS It is recommended that 1. Surveys similar to those performed for Greenhouse and Ivy are probably worth the effort on future major shots, since they require little more than standard surveying techniques. 2. Since the dynamic behavior of crater formation has not been determined, some further © insight can probably be gained by an attempt to measure one crater as soon as possible after zero time. 3. Future crater studies at Eniwetok should consider details of geologic structure in interpreting the data. craters, it is to be expected that the small en- REFERENCE 1, F. B.
