Book Description
Core samples from all three holes examined thusly over 1-ft intervals revealed these microfractures to occur consistently at points 35-38 ft radially from the shot point. A radius of 36+2 feet is therefore assigned to the explosion cavity. The true crater (cavity) surface is a hemisphere radially symmetrical about the shot point at depths below approximately 110 ft. Fixing this radius relative to calculated cavity expansion curves and to the probable time of venting aids in the understanding of history and mechanisms of cavity growth, from which speculative treatments of the behavior of rock and water vapors in the growing cavity and of a possible origin of vesiculated glass found in the crater throwout rubble have been developed.

Book Description
The results of various previously reported investigations of the Danny Boy event are utilized to compute and compare the volumes of ejected material and volumes attributable to other crater-formation mechanisms. Imbalance of the volumetric contributions is attributed primarily to the uncertainty of the ejecta density in the lip region. Approximately 65 percent of the rock material dissociated by the explosion was permanently ejected from the crater; less than 2 percent of the ejected material was deposited beyond 3 crater radii from ground zero. Comparisons are made with high-explosive and nuclear detonations in desert alluvium. (Author).
