The effects of underground explosions are considered, first for deep explosions far from a free surface, then for shallow explosions which form craters and eject debris. The general pattern of behavior is established from compilations of test data for typical rocks and soils, and comparable compilations are made for the more limited test data relating to frozen soils, ice and snow.
