Fig. 13From: Application of scattering theory to P-wave amplitude fluctuations in the crustDifferences in amplitude level variance between spherical and plane waves. Ratio of amplitude level variance for spherical waves to that of plane waves for wavenumber values of π/4, π/2, π, 2π, and 4π km−1. Stochastic parameters a = 1 km and ε = 0.03 are assumed. The dotted line indicates the region in which data are at saturation levelBack to article page
