In this study, we computed tsunami propagation and inundation considering a scenario earthquake along the Arakan Trench. We assumed 10 tide gauge stations along the west coast of Myanmar for Tsunami waveform computation. We assumed a scenario earthquake (MW 8.7) along the Myanmar subduction zone off the west coast of Myanmar. The seafloor deformation was computed based on the nine static fault parameters. The top depth of the fault was assumed as 0 km. The length of the fault was 358.8 km, width of the fault was 100 km and slip of the fault was 17m. The strike, rake and dip angles of the fault were set to be 341 degree, 127 degree and 10 degree, respectively. The tsunami propagation and inundation modeling based on the TUNAMI_N2 model (Tohoku University’s Numerical Analysis Model for Investigation of Near-field No.2), was used in this study with GEBCO 1 arc-min bathymetry data set. The bathymetry of the region was obtained from GEBCO 30 arc-sec data, and also from coastal topography data of Shuttle Radar Topography Mission (SRTM). We performed tsunami inundation modeling around Chaung Thar beach and Ngwesaung beach. Chaung Thar beach (hotel zone) and Chaung Thar village were affected by the tsunami wave with an inundation height from 0.3 m to 4.2 m and inundation area extent from 70 m to 140 m. Ngwesaung beach was affected by the tsunami wave with an inundation height from 0.2 m to 7.6 m and inundation area extent from 70 m to 140 m.
