From: Seismic imaging and petrology explain highly explosive eruptions of Merapi Volcano, Indonesia
South-North vertical sections across Merapi and Merbabu. (a) Vp, (b) Vp/Vs, (c) Vs, (d) checkerboard recovery for Vp, and (e) same as (d) but for Vp/Vs. The input pattern of the checkerboard test is shown in the inset in (e) with input perturbations of X = 10% for both Vp and Vp/Vs as in Fig. 2. Vp and Vs are plotted as perturbations with X = 12% relative to the 1D model based on Koulakov et al.18 and X = 5% for the checkerboard recovery for Vp and Vp/Vs; while Vp/Vs is plotted as absolute values.
