Spallation of the ground surface accompanies all underground nuclear explosions of significant yield. This report discusses computer modelling used to investigate the physical processes that govern spallation and the amplitude and wavelength of motion at the free surface under a variety of conditions. Four events are selected: MERLIN which was conducted in desert alluvium; HEARTS which was conducted in tuff beneath the water table in Yucca Flat; TOWANDA which was conducted beneath the water table on Pahute Mesa; and HOUSTON which was conducted above the water table in very dense rock and Pahute Mesa. These span the range of test environments for Los Alamos underground nuclear tests.
