Abstract—This paper analyzes the spatial distribution of residual deformations generated at the surface of a
rock mass (massif) by underground nuclear explosions and their relationship to the present-day hierarchical
block-fault structure of rock masses. The specific block-fault structure at the Novaya Zemlya Test Site affects
the magnitude, orientation, and type of postblast residual deformations. The largest postblast deformations
(within a specific radius) are observed in fault zones of a definite rank.
