Coseismic Deformation Responses due to Geometrical Structure and Heterogeneity of the Accretionary Wedge: Study Case 2010 Mentawai Earthquake, West Sumatra, Indonesia

Figure 4

The density and rigidity resulted from the Vp and Vs values in Figure 3. (a) The density of the accretionary wedge (gray line), continental plate and mantle (blue line), and oceanic plate and mantle (orange line). (b) The rigidity of the accretionary wedge (gray line), continental plate and mantle (blue line), and oceanic plate and mantle (orange line). (c) The density of the accretionary wedge for the single material variation model obtained from Vp variation (5.1-5.7 km/s) and Vp/Vs ratio 1.6 (black dot), 1.7 (pink dot), 1.8 (yellow dot), 1.9 (gray dot), 2.0 (blue dot), 2.1 (green dot), and 2.2 (red dot). (d) The rigidity of the accretionary wedge for the single material variation model obtained from Vp variation (5.1-5.7 km/s) and Vp/Vs ratio 1.6 (black dot), 1.7 (pink dot), 1.8 (yellow dot), 1.9 (gray dot), 2.0 (blue dot), 2.1 (green dot), and 2.2 (red dot).
