Three Dimensional Numerical Simulation of Tsunami Generation and Propagation Due to Makran Subduction and run-up on Chabahar Bay and Makran Coasts
Authors
Abstract:
Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD based software of Flow 3D is applied for global and regional numerical simulation of tsunami wave propagation. In the first stage the 3D propagation of the wave in Oman sea and Indan Ocean is simulated. The presented approach in this paper including the accurate 3D generation of the tsunami wave using the Okada algorithm and two stages propagation in the global and regional models results in a more accurate results in terms of time duration and tsunami wave run-up.

Statistical Analysis of Earthquakes and Tsunami of Makran Subduction Zone (MSZ), and Tsunami Hazard Assessment of Gwadar Coast
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 ...

The recent studies show that the past researches may have significantly underestimated earthquake and tsunami hazard in the Makran Subduction Zone (MSZ) and this region is potentially capable of producing major earthquakes. In this study, the worst case possible earthquake scenarios of the MSZ are simulated using fully nonlinear boussinesq model to investigate tsunami hazards on the Jask Port, ...

Extreme coastal inundation associated with the 2004 Indian Ocean and 1945 Makran tsunamigenic-earthquakes highlight the risk of tsunamis to coastlines of the northern Oman Sea. Foraminifera have been used as indicators of paleotsunamis in the past where allochthonous tests, found in low-energy environments such as in coastal lagoons, ponds, and marshes, indicate marine overwash. In this study, ...

makran subduction zone (msz) offshore of iran and pakistan is one of the most tsunamigenic sources in the indian ocean. historically, the msz has generated some tsunamigenic earthquakes like that of 28 november 1945 with the death tool of more than 4000 people along the coasts of iran, pakistan, india, and oman. in this study, the tsunami hazard associated with the msz is investigated. at first...

This study has been carried out in the coast of Chabahar Bay from March, 2013 to Febuary, 2014. We sampled macrofouling organisms in three stations. Overall, 40 species of macrofouling organisms were detected in which Barnacles, sponges, Bryozoans, echinoderms, Polychaetes and Gastropods were the major groups. The majority of biomass and highest density were observed in the first half of the se...
