Coğrafi bilgi sistemı ile analitik hiyerarşi süreci kullanarak deprem risk değerlendirmesi: Eskişehir, Türkiye

This study aimed to assess the seismic risk using geographical information system with the used of Analytic hierarchy process in the province of Eskişehir, Turkey. Specifically, this paper sought to answer which area in the province of Eskişehir is highly prone to earthquake based on lithology, fault lines, and epicenter. Based on the three criteria, which area of the province is highly prone to earthquake. Lastly, based on GIS and AHP, which among these three factors produce the same result of computation of risks. The result of the study creates different suggestions for the Disaster Risk Reduction Management Program of the province. First, based from lithology, the result in AHP method shows that the district of Çifteler and Alpu has the highest risk of earthquake seismicity while the result of GIS method shows that the district of Tepebaşı has the highest risk of seismicity in Eskişehir province. Second, based from fault lines, the result in AHP method shows that Tepebaşı has the highest risk of seismicity while based on GIS method, the district of İnönü, Mihalgazi, Tepebaşı, and Sarıcakaya has the highest risk of seismicity. Third, based on epicenter, the result in AHP method shows that Tepebaşı has the highest risk of seismicity while based on GIS method, the result shows that İnönü, Sarıcakaya, and Alpu has the highest rate of seismicity. Fourth, using the three scenarios, the result shows that the district of Tepebaşı and İnönü has the highest rate of seismicity in the province of Eskişehir. And lastly, based on GIS and AHP method, the result of scenario three produce a similar seismic risk in the district of Tepebaşı.
