Fig. 3From: Application of scattering theory to P-wave amplitude fluctuations in the crustHypocentral distance variations for amplitude level variance: von Kármán-type random media. a Power spectral densities of von Kármán-type random media with different β values. b Hypocentral distance variations for amplitude level variance in an acoustic von Kármán-type media with different β values. Stochastic parameters a = 1 km and ε = 0.03 and wavenumber k=π km−1 are assumed. The dotted line indicates the saturation level where log-amplitude variance tends toward a constantBack to article page
