“…Records indicate that large earthquakes occur frequently in Izmir, the latest in 1778. Main Highlights of the Earthquakes and related fault zones in Izmir Region is shown in Figure 3 [8][9][10]. Considering its location and urban features, the city of Izmir, a port, has come to be one of the leading symbols of cultural and historical heritage.…”

Structural Vulnerability assessment of historical buildings is very important to carry them to the future. Turkey is a rich country in terms of historic masterships mostly from Ottoman Empire, such as mosques, bathhouses, churches and aqueducts. Especially mosques are the common historical structures in turkey. Therefore, in the present study, structural vulnerability assessment of historical mosques in Turkey was carried out. One of the existing ones is considered as a sample building and structural vulnerability assessment was carried out on this building. The sample building was selected as Konak Mosque located in Izmir, Turkey. The mosque was structurally investigated through advanced approaches. The mosque, constructed in 1755 by Ottoman at very central location close by the clock tower, is little one decorated with blue tiles. The mosque is also nearby a historical bazaar where the main historical business stream line is located. Konak Mosque is one of these new styles in that age. It can be named as a signature historical building representing Islamic minimalist oriented architecture with its unique octagonal plan. In the present study, the building was modelled by using the Finite Element Modelling (FEM) software, SAP2000. Time history analyses were carried out using 10 different ground motion data. Displacements, base shear and stress values were interpreted and the results were displayed graphically and discussed. For probabilistic seismic risk assessment, fragility analyses were also carried out and the fragility curve and surface were sketched for the mosque. Saddle point was determined on the fragility surface.

“…The danger posed to civilization by devastating earthquakes in many regions of the globe is sufficient justification for evaluating the seismic hazards of earthquakes while constructing buildings and infrastructures [1,2,3]. As a result of the region's high seismic activity, a number of researchers have evaluated the seismic hazard of several areas in southwest Turkey [4,5,6,7,8]. The Burdur Basin and its environs are situated in a region that has seen high seismic activity over both the historical and instrumental periods [9].…”

The aim of this study is to assess seismic hazard for Burdur City (SW Turkey) using a probabilistic approach. A new earthquake catalog for Burdur City and its vicinity, with unified moment magnitude scale, was prepared in the scope of the study. Seismicity of the area was evaluated by the Gutenberg-Richter recurrence relationship. For hazard computation, R-CRISIS (v18) software was used. New Generation Attenuation models were used for analyses. Seismic hazard maps were developed for peak ground acceleration and for bedrock with hazard levels of 2% and 10% probability of exceedance in 50 years. Results of the study show that peak ground acceleration values on bedrock with hazard levels of 2% and 10% probability of exceedance in 50 years change between 0.70-0.75 g and 0.44-0.48 g, respectively.

Earthquakes are one of the most unpredictable natural disasters. A series of secondary and derived disaster events may occur afterwards and lead to even more consequences. In such situations, a seismic risk analysis that takes into account secondary and derived disaster events is vital in reducing the risks of such disasters. The absence of a holistic seismic risk analysis model—one that takes into account the derived disaster events—may mean that the serious consequences of the disaster chains set off by earthquakes are neglected. This article proposes a comprehensive seismic risk analysis that enables a better understanding of seismic disaster chains and rescue scenarios. The approach is based on a Bayesian network constructed using scenario‐based methods. The final network structure is achieved by learning parameters. To determine the critical secondary disasters and the key emergency‐response measures, probability adaptation and updating using the Bayesian model were performed. The practical application of the model is illustrated using the Wenchuan earthquake and the Jiuzhaigou earthquake in China. The two examples show that the model can be used to predict the potential effects of secondary disasters and the final seismic losses. The results of the model can help decisionmakers gain a comprehensive understanding of seismic risk and implement practical emergency‐rescue measures to reduce risk and losses.
