Close-In Air Blast From the Cabriolet Event

: Results are given of pressure-time measurements measured by two gages at each of eight stations from surface ground zero to 6000 feet on the Cabriolet event. The largest overpressures resulted from the air-transmitted ground-shock-induced pulse and were comparable to those measured on the Danny Boy and Sulky events. There is evidence that for underground explosions as for aboveground explosions the air blast from a 1-kiloton nuclear explosion is comparable to that from 1/2 kiloton of TNT. The weak pulse from venting gas was also comparable to those from Danny Boy and Sulky and all were well below those from comparable TNT explosions. Comparisons between airblast from Cabriolet and that from Palanquin in the same medium are made.
