Makran zone is one of the largest accretionary wedges in the world. This research had used methods such as studies of Office and library, field observation and surveying that several field visits, sampling, registered structural evidence, Laboratory studies, Data analysis, interpretation and conclusions. The most important objective of this study is assessment of Tectonics and hazard Potential in Coasts the Oman Sea based on tectonics and sedimentology. The northward movement and subduction of Oman oceanic lithosphere beneath Iranian micro-plate at a very shallow angle and at high rate is responsible for active orogenesis and uplift. Detailed seismological and geological information in planning is extremely essential to avoid any disaster. It is to be remembered that seismicity does not remain fixed in an area but migrates slowly with time. Thus, the planners are expected to be more concerned with the building code and prevention strategies. It is also important to mention that the Coastal zones are always vulnerable to natural hazards and liquefaction. The geomorphology of an area is the first indicator of on-going tectonic activity. In order to measure the amount of deformation due to tectonic processes, the initial geometry of the geomorphic markers is reconstructed accurately. Study of sediments shows that abundant shell fragments organized in laminae also favor a storm origin. Storm deposits contain no internal mud layers and rarely contain pieces of mud. Maximum deposit thickness is near the shore, and landward thinning of the deposit is commonly abrupt. Storm deposits fill in topographic lows, and the upper surface is relatively uniform in elevation alongshore. Finally, landforms of tectonically active regions and sediments are controlling factors interactions between tectonic, sedimentary, climatic, and surficial processes.
