Fig. 2: Anisotropy of the classical and nonclassical effects.
From: Anisotropy reveals contact sliding and aging as a cause of post-seismic velocity changes
Results of the fitting of the classical β and nonclassical δ parameters to the transverse isotropy law in Equation (1). Dots indicate measurements resulting from direct P-wave arrivals; stars are for reflected P-wave arrivals. Color of symbols shows uncertainty of individual measurements. The red curve is the average model with orange bands indicating the 95% confidence interval. The histograms show the results of the 5000-iteration bootstrap sampling inversion of the u and v coefficients.
