Elastic shock waves in a viscous-fluid-saturated porous medium are investigated. The porosity is only taken into account with respect to pores communicating with one another; and isolated pores are considered as elements of the elastic part of the porous skeleton. It is shown; using the theory of discontinuity; that in such a medium there are two types of vortex-free waves and one equivoluminal wave. Differential equations and their solution for determining the change in the wave-front intensity are obtained. The effect of the fluid viscosity and porosity on the propagation of spherical waves is demonstrated using an example. ©2015 Elsevier B.V. All rights reserved;
