We present a detailed introduction to radiative transfer in seismology. Starting from the well-known phenomenological approach for acoustic waves, the theory is then generalized to elastic waves, including the treatment of polarization and mode conversions. The last part of the paper presents a rst-principle derivation of the acoustic transfer equation. The fundamental quantities of transport theory such as the speci c intensity and the mean free path are then rigorously de ned in terms of the statistical properties of the medium and wave eld. Some applications of the theory are discusse
