Tsunami Hazard Assessment on Qatar Coastline from Makran Earthquakes Considering Tidal Effect and Coastal Landslides Scenarios

To assist the analysis of tsunami hazards for Qatar coastal areas were using numerical model. By Tsunamis waves created from submarine earthquakes magnitude (Mw) 8.6 and 9.0 in Richard scale along Makran Subduction Zone (MSZ) as well landslides with soil volume 1.25 to 2.0 km3 Iranian coast inside Arabian Gulf is considered. TUNAMI-N2KISR model (Al-Salem) was applied this study predict propagation Tsunami induced wave heights. The adopts solve shallow water equations describing nonlinear long-wave theory. also incorporate tidal effect a travel time coastline takes more than 9 hours range about 1.6 m during Spring Tide event. For landslides, generation simulated two-layer model, developed by solving equations. Two-layer used determine initial deformation generated landslide case. Then use simulate propagation. scenario arrived after 2.5 - 3 hr maximum amplitudes coasts Ras laffan-Qatar 0.8 1.0 m. Incorporation ocean tide found impose some small on amplitude at nearby Mw earthquake due area. In addition, it that arrival has become shorter.
