Niksar (Tokat) is an urban area located in a seismically active zone of Turkey. The aim of this study is to prepare a GIS-based microzonation map of the Niksar settlement area for the purpose of urban planning. Liquefaction, activity, slope, aspect, fault proximity, ground amplification, and lithology are considered during the overlay analysis, using a multicriteria decision-making analysis of the analytical hierarchy process (AHP) and simple additive weighing (SAW) methods. Based on the resulting evaluations, the study area is divided into four different zones, namely (1) areas suitable for settlement, (2) provisional settlement areas, (3) areas requiring detailed geotechnical investigation, and (4) unsuitable areas. Maps prepared by the SAW and AHP methods are found to be consistent with each other. However, the microzonation map prepared by the AHP method is recommended for the purpose of urban planning because it is able to check its own consistency.

Gis-based microzontion of Niksar (Tokat) settlement area for the purpose of the urban planning Erol, Gökhan; Topal, Tamer; Department of Geological Engineering (2009) Niksar (Tokat), is an urban area located in a seismically active zone of Turkey. The aim of this thesis is to prepare GIS-based microzonation map of Niksar settlement area for the purpose of urban planning. Liquefaction, activity, slope, aspect, fault proximity, ground amplification and lithology are considered during the overlay analysis by using Multicriteria Decision Making Analysis (MCDA) of Simple Additive Weighing (SAW) and Analytical Hierarchical Process (AHP) methods. Based on the evaluations, the s...
Use of Ground Motion Simulations of a Historical Earthquake for the Assessment of Past and Future Urban Risks Çelik, Aylin; Karimzadeh, Shaghayegh; Askan Gündoğan, Ayşegül (2018-09-02) Erzincan city located in the Eastern part of Turkey at the conjunction of three active faults is one of the most hazardous regions in the world. In addition to several historical events, this city has experienced one of the largest earthquakes during the last century: The 27 December 1939 (Ms=8.0) event. With limited knowledge of the tectonic structure by then, the city center was relocated to the North after the 1939 event by almost 5km, indeed closer to the existing major strike slip fault. This decision ...

Characteristics of earthen architecture in ağlasun Kurtulus, V.b.; Asrav, E.ç.; Şahin Güçhan, Neriman; Altınöz, G. Bilgin (null; 2018-01-01) Ağlasun is a rural area in Burdur, on the west Mediterranean Region in Turkey. Most of the buildings in Ağlasun is built with the materials provided from the local resources except the ones effected from the industry of reinforced concrete. The commonly used materials in the vernacular constructions are mud-brick and stone. The specialty that makes the earthen buildings in Ağlasun unique is their respectable structural condition although they are more than 60 years old. Plan layout of the buildings which re...
