Assessing extracted profiles from the Caspian sea bottom between Anzali port and the Sefidrood estuary reveals a sedimentary mass as a source of contingent transitional landslide and so tsunami is located in front of the mouth of the Sefidrood River. In this study, after estimating the characteristic and mass of this contingent landslide, the tsunami caused by this source is simulated using GEOWAVE model. Model outputs illustrate the initial tsunami wave is very high, but damps rapidly as it propagates to the shoreline. The tsunami causes relatively high waves to reach the shores which adjacent to the landslide and creates significant raises. The probability of the tsunami reaching to far and densely populated areas due to the landslide is very low. It can be related to the limited effect of landslide tsunamis due to radial depreciation and dispersion. Therefore, it is concluded the Iranian coasts is safe from the tsunami.
Keywords: Caspian Sea, Tsunami, Submarine landslide, GEOWAVE, Sefidrood Estuary.
