Tsunami wave transmission simulated using assumption of four synthetic faultblocks moving simultaneously in the south of Java Island to examine the tsunami height distribution influenced by the bathymetry along with their trajectory courses toward the shoreline. Tsunami wave transmission modeling was conducted using COMCOT v 1.7 with 1 hour time constraint. The simulation shows that the tsunami heights in the area around peninsula, bay, shoreline, and offshore with gentle bathymetry tend to be higher than surrounding areas due to wave transformation processes from deeper bathymetry depths to shallower ones. The simulation also shows that places like Pelabuhan Ratu and Sindangbarang, which have steeper bathymetry compared to gentler Pangandaran Beach, would have developed their tsunami height earlier. It is expected that this simulation can become a reference to predict the tsunami height and arrival time in other places which have similar bathymetric profile characteristic.
