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

Figure 1

Maps of the study area. (b) The map of Indonesia in general. Our study area is the Sumatra subduction in the western part of Indonesia. The blue rectangle shows the size of the model used in our simulation. Our focus study area (a), the Mentawai segment, shown in black rectangle on the map (b). The red star indicates the epicenter of the 2010 Mentawai earthquake. The green triangles are the SuGAR GPS station which the data are used for this study. The coseismic slip model used in this study is from Hill et al. [35]. The black line is the cross-section used for Figure 7. The scale bar at the bottom of the map shows the scale of the bathymetry and the topography in meters.
