Tsunami waves are the most underrated hazard affecting the life near coastal belts. With socio-economic developments in coastal region results in more hazardous from tsunami. The hazard assessment of tsunami is highly vital. The Makran region is exceptional in closure zone of Tethys; it is only segment east of the Mediterranean and west of Andaman arc in which subduction of oceanic lithosphere is still an ongoing process. The objective of present study highlights the seismicity of MSZ. It also describes the statistical analysis of the earthquake events after 1973 for the study area, and possible tsunamigenic effects on Gwadar Coast. Fault plane solutions are also correlated with structural map of the study area and delineated the neo-tectonic features. I also try to determine the tsunami hazard assessment, run-up, inundation, maximum sea surface height and first arrival time of the incident waves and amplitude.
ComMIT is used to calculate tsunamigenic parameters at Gwadar coast. The tsunami hazard assessment describes the possible hazardous incidents in near or far future for the coastal area. The velocity estimation of tsunami waves at Gwadar coast depict that, waves have higher velocities. The impact of the tsunami waves will be more at the inner thin portion (Zone-A) of study area having an average elevation of 2 to 3 meters.
