The paper presents the results of numerical studies of seismic source of an underground nuclear explosion affected by the environment, namely, rock massive geology, concavity or convexity availability, depth and yield of the explosion, the initial state of stress in rock (hydrostatic or tensor) etc. A study is made of the feasibility of seismic signal attenuation with a loweryield explosion at a greater depth.

A technique is developed for modeling the seismic source of an underground nuclear explosion in a large air cavities without considering radiation transfer. The data from adiabatic calculations of decoupling of explosions in cavities filled with air or porous material in axially symmetric formulation with horizontal rock lamination are presented. The impact of the cavity shape and charge location upon decoupling has been studied.
