Excitation and radiation of seismic waves in poroelastic media are analyzed. Based on the Fourier transform method we derive the fundamental solutions (Green’s functions) of dynamic poroelasticity. In analogy to the elastodynamic problem, the representation of the results allows identification of near- and farfield terms.<br>It is shown that seismic sources in poroelastic media can be consistently described with moment tensors.<br>The results are illustrated with help of radiation patterns for various source types. Synthetic seismograms of the slow P-wave mode demonstrate the importance of viscous dissipation in seismic modeling of poroelastic structures.
