DANNY BOY EVENT. PROJECT 1.6: MASS DISTRIBUTION MEASUREMENTS OF CRATER EJECTA AND DUST POR 1815 (WT), APPENDIX B. VOLUMETRIC EQUALITIES OF THE CRATER

Abstract

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.
