This study assesses the landslide susceptibility of the South Pars Special Zone (SPSZ) region that is located in southwest Iran. For this purpose, a combinatorial method containing multi-criteria decision-making, likelihood ratio and fuzzy logic was applied in two levels (regional and local) at three critical zones (northwest, middle and southeast of the project area). The analysis parameters were categorised in seven main triggering factors such as climatology, geomorphology, geology, geo-structure, seismic activity, landslide prone areas and man-made activities which have different classes with multi-agent partnership correlations. Landslide susceptibility maps were prepared for these levels and zones after purified and enriched fuzzy trending runs were performed. According to the results of the risk-ability assessment of the landslide occurrences for SPSZ, the north part of the study area which includes the south edge of the Assalouyeh anticline and the southern part of the Kangan anticline were estimated as high-risk potential areas that were used in landslide hazard mitigation assessment and in land-use planning.

Geotechnical characteristics and empirical geo-engineering relations of the South Pars Zone marls, Iran
Azarafza, Mohammad; Ghazifard, Akbar; Akgün, Haluk; Asghari-Kaljahi, Ebrahim (2019-12-10)
This paper evaluates the geotechnical and geo-engineering properties of the South Pars Zone (SPZ) marls in Assalouyeh, Iran. These manly beds mostly belong to the Aghajari and Mishan formations which entail the gray, cream, black, green, dark red and pink types. Marls can be observed as rock (soft rock) or soil. Marlstone outcrops show a relatively rapid change to soils in the presence of weathering. To geotechnically characterise the marls, field and laboratory experiments such as particle-size distributio...
Volcano stratigraphy and petrogenesis of the Nemrut stratovolcano (East Anatolian High Plateau): The most recent post-collisional volcanism in Turkey
Ozdemir, Y; Karaoglu, O; Tolluoglu, AO; Güleç, Nilgün Türkan (Elsevier BV, 2006-02-28)
The Nemrut stratovolcano, with its well defined summit caldera, is the most recent volcanic eruption center (1441 A.D.) in the East Anatolian High Plateau, one of the best examples of an active colllision zone. Widespread volcanism has been active in this region for the last similar to 10 Ma, producing large volumes of lavas and pyroelastics covering a broad belt, across the Bitlis Suture Zone, from the Anatolian plate in the north to the Arabian plate in the south.
Landslide susceptibility mapping: A comparison of logistic regression and neural networks methods in a medium scale study, Hendek region (Turkey)
Yesilnacar, E; Topal, Tamer (Elsevier BV, 2005-07-01)
Landslide susceptibility mapping is one of the most critical issues in Turkey. At present, geotechnical models appear to be useful only in areas of limited extent, because it is difficult to collect geotechnical data with appropriate resolution over larger regions. In addition, many of the physical variables that are necessary for running these models are not usually available, and their acquisition is often very costly. Conversely, statistical approaches are currently pursued to assess landslide hazard ove...
Numerical analysis and stability assessment of complex secondary toppling failures: A case study for the south pars special zone
Azarafza, Mohammad; Bonab, Masoud Hajialilue; Akgün, Haluk (2021-12-01)
This article assesses and estimates the progressive failure mechanism of complex pit-rest secondary toppling of slopes that are located within the vicinity of the Gas Flare Site of Refinery No. 4 in South Pars Special Zone (SPSZ), southwest Iran. The finite element numerical procedure based on the Shear Strength Reduction (SSR) technique has been employed for the stability analysis. In this regard, several step modelling stages that were conducted to evaluate the slope stability status revealed that the mai...
Tsunami risk assessment using GIS-based multi criteria decision analysis at Bakirköy, İstanbul
Tüfekçi, Duygu; Süzen, Mehmet Lütfi; Yalçıner, Ahmet Cevdet; Department of Geological Engineering (2016)
Northern coast of the Sea of Marmara hosts many of coastal facilities. Bakırköy is one of the most critical coastal districts of İstanbul with the importance of air and marine transportation. There are many other coastal facilities and structures in Bakırköy district such as marinas, small scaled craft harbors, water front roads and business centers that are prone to suffer from the marine disasters. In the history, the Sea of Marmara has experienced numerous earthquakes and associated tsunamis. Therefore, ...
