Bedrock depth and vertical cross-section of JIVSM (Koketsu et al. 2012). (Top) The spatial distribution of the bedrock depth (top depth of VS = 2.9 km/s) in and around the study area. The broken rectangle represents the geographical area modeled in our FDM simulation. (Bottom) Cross-section of the S-wave velocity model in JIVSM along the line D–D′. The open star denotes the hypocenter of the mainshock located by JMA
