This study investigates the scaling of dimensions of craters formed by nuclear explosive sources as well as the problem of making consistent estimates of other geonuclear effects including maximum base surge radius, vented fraction of the gamma emitting radionuclides appearing in close-in fallout, and main cloud dimensions. Input to the proposed scaling method includes the Froude number as determined by the depth of burial and the mound surface velocity at vent time, and the pressure in the cavity at vent time. These inputs are provided from long-running cratering-mechanincs numerical calculations. Illustrations are given of the use of the method for 1 Mt and 200 kt cratering events. 10 refs., 10 figs., 7 tabs.
