Abstract:

This study examines near-field observations of spalling, a phenomenon associated with most underground nuclear explosions, and attempts to estimate its effects on m sub b and M sub s. Observations of spall on near-field accelerometers and partical velocity records were used to examine possible relationships between radius of spallation, estimated spall thickness, maximum height attained by spall at the surface, shot depth of burial and yield.
