In applied geophysics, it is usually needed to simulate the propagation of waves in a bounded region of the subsurface. This requires the use of absorbing boundary conditions at the artificial boundaries of the subsurface model so that spurius reflections be mimimized. This Chapter presents the derivation of this type of absorbing boundary conditions in elastic and poroelastic media. They will be used later in the Chapters dedicated to simulate wave propagation phenomena.
