STUDY ON TSUNAMI FLOOD OCCURRENCE DUE TO MAKRAN SUBDUCTION ZONE (CASE STUDY BERIS

According to scientific and historical evidences, MAKRAN subduction zone has high destruction potential due to making tsunami in southeastern coasts of Iran. So, studying andsimulating tsunami flood due to probable earthquakes in MAKRAN subduction zone at SISTAN & BALUCHESTAN coasts, especially in Port BERIS is so important. In this research, tsunamisflood on MAKRAN subduction zone was simulated and studied on SISTAN &BALUCHESTAN province coasts at Port BERIS by using COMMIT software. Various cases on this research were 8, 8.5 and 9 Richter earthquakes. Result shows that maximum run-up for thisregion for 8, 8.5 and 9 Richter earthquakes are 0.5 m, 3.4 m and 14 m. In addition, maximumflood width is close to 1.4 km and the time of first arriving waves to coast is around 22 min. the results of this research can be used in structure plan of the region
