Hypocentral distance variations for amplitude level variance: random inhomogeneous media. Hypocentral distance variations for amplitude level variance in a random inhomogeneous media using medium model A and the no. 1 and 6 source time functions for FDM simulations. Grey circles denote simulation results. Solid lines indicate theoretical evaluations by Eq. (13). The dotted line indicates the saturation level where log-amplitude variance tends toward a constant
