Country of Origin: United States Country of Publication: United States Abstract: The craters from high-yield nuclear tests at the Pacific Proving Ground are very broad and shallow in comparison with the bowl-shaped craters formed in continental rock at the Nevada Test Site (NTS) and elsewhere. Attempts to explain the difference in terms of dewice yield (which was much larger in the Pacific tests than at NTS) have’ been generally unsatisfactory. We have for the first time successfully modeled the Koa Event, a representative coral-atoll test. On the basis of plausible assumptions about the geology and about the constitutive relations for coral, we have shown that the size and shape of the Koa crater can be accounted for by subsidence and liquefaction phenomena. If future studies confirm these assumptions, it will mean that some scaling formulas based on data from the Pacific will have to be revised to avoid overestimating weapons effects in continental geology. 41 references, 10 figures, 1 table.; Major Descriptors: *CRATERS ~- GROUND SUBSIDENCE; *NUCLEAR WEAPONS ~-- BLAST EFFECTS Descriptors: CORALS; CRATERING EXPLOSIONS; ENIWETOK Broader Terms: CAVITIES; CNIDARIA; EXPLOSIONS; ISLANDS; MARSHALL ISLANDS; MICRONESIA; OCHANIA; WEAPONS Subject Categories: 450202* Weaponry ~~ (-1989) 10/5/659 01499529 -- Explosions & Explosives -- Nuclear ~-- (Item 359 from file: EDB~85-006287 103) Title: Operation Greenhouse.
