This atlas includes a comprehensive multidisciplinary study of all physical, chemical, biological, geological oceanography, pollution and hydrodynamics in the southern Caspian Sea. In physical oceanography, various parameters of temperature, salinity, dissolved oxygen, turbidity, and chlorophyll-a were measured seasonally. In the chemistry section,...

This study examines a significant accumulation of deposits on an abnormal slope in the southern Caspian Sea, which is believed to be a potential source of submarine landslides due to seismic activity in the faulting system of the northern Iranian plateau. A presumed earthquake Mw 7.7 originating from the Khazar Fault is identified as the triggering...

The Makran Subduction Zone (MSZ) is one of the world's most tsunami-prone regions. In the present study, tsunami hazards associated with potential MSZ earthquakes are evaluated using stochastic earthquake rupture modeling, which allows for the incorporation of uncertainties related to slip heterogeneity. Along the western segment of the MSZ, where...

Recently, recorded profiles have been extracted from the Caspian sea bottom between Anzali port and the Sefidrood estuary using echo sounders .Assessing the profiles reveals a sedimentary mass that it can be considered as a source of contingent transitional landslide and so tsunami, the mass is located approximately in front of the mouth of the Sef...

The present study focused on tracing tsunami-drifted objects under a real tsunami based on an integrated numerical method. Instead of a solitary wave that is much shorter and steeper than real-world tsunami waves, an extra-long tsunami wave is represented here in a nearshore region using a new approach. To this end, propagation of a seismic tsunami...

In this study two numerical models, one a regional generation and propagation model and the other an inundation model, have been applied to the problem of examining the impact that a large, locally generated tsunami could have on Chabahar Bay facilities in Iran. To achieve a realistic outlook of tsunami hazards in the area, the generation, propagat...

A case-study pertaining to a number of existing breakwaters located on northern coastlines of the Gulf of Oman, directly facing the Makran Subduction Zone (MSZ) sets the context in order to elucidate the adopted methodologies for both Probabilistic Tsunamis Hazard Analysis (PTHA) as well as investigating breakwater stability in the event of a major...

The Makran subduction zone (MSZ), located along the southern coasts of Iran and Pakistan, has experienced some deadly earthquakes and tsunamis, including the destructive 1945 Makran tsunami that led to more than 4000 fatalities. In spite of past studies on 1945 Makran tsunami, there are still unresolved problems, particularly on mismatches between...

Subduction zone earthquakes have been considered as the tsunami source in most of the previous studies of Caspian Sea tsunamis and the result of a submarine landslide has been less investigated. A probable tsunami generated by a submarine landslide, located in Derbent Basin of the middle part of Caspian Sea, is studied in this research. The effect...
