Hypocentral distance variations for amplitude level variance in different random inhomogeneous media. Hypocentral distance variations for amplitude level variance in different random inhomogeneous media using medium models A and B and the no. 8 source time function for FDM simulations. a Results of FDM simulations for acoustic and elastic media. Grey circles show simulation results. Solid lines indicate theoretical evaluations by Eq. (13). The dotted line indicates the saturation level where log-amplitude variance tends to a constant. b Ratio between amplitude level variance for medium model A (acoustic medium) and medium model B (elastic medium)
