SUMMARY After the two devastating earthquakes in the Marmara Region of Turkey in August and September of 1999, several disaster and emergency management agencies have been established and several activities have been carried out. This paper summarizes those activities in Turkey. Management of disasters or emergency situations is to conduct preparedness, mitigation, response and recovery activities in a cycle to save life first and then save property. All the stages of this cycle give outputs according to the inputs entered. The quality and the effectiveness of the output acquired from the cycle depend on the quality and detail of the input given to system.

SUMMARY The proposed study considers the interdependency concept on seismic performance analysis of lifeline network systems. Seismic damage estimates of the electric power, potable water, and natural gas networks of the city will be calculated for the expected Marmara earthquake scenario and the results will be utilized to assess the performances of the topological models of the networks. The study will first include collection of lifeline utility network data in GIS format. Seismic damage analysis will be made by defining fragilities of the network components and the ground motions generated by the scenario earthquake. The gathered network datasets will be topologically modeled. The damage estimates will be utilized in the topological model to obtain the post-seismic state of the networks for performance analysis. Two interdependent network performance measures, named connectivity loss and service flow reduction, will be applied to the networks in order to predict the effect of th...

ABSTRACT The creation of earthquake hazard maps requires various datasets with selected attenuation relations. Based on the selected attenuation relation, the calculation time varies from half an hour to a couple of days. The length of time needed to create an earthquake hazard map also depends on the resolution of the resulting map. The time gets longer as the resolution of the resulting earthquake hazard map gets higher. The basic form of an attenuation relation requires complex calculation algorithms including geospatial infor-mation related to the region of interest. Nowadays, next-generation attenuation (NGA) models are introduced to generate more realistic earthquake hazard maps. However, the more complex the attenuation relation is, the longer time will be required to create a hazard map. This paper offers a new method to create high-resolution earthquake hazard maps, faster than using traditional attenuation relation methods, by using an analytic hierarchy process of spatial multi-criteria decision analysis and geographic information systems. This method has been generated and tested for the city of Istanbul. The resulting maps are compared with the earthquake hazard maps created for the city of Istanbul by using the NGA model of Boore and Atkinson (in Boore–Atkinson NGA ground motion relations for the geometric mean horizontal component of peak and spectral ground motion parameters (trans: Engineering Co, University of California B). Pacific Earthquake Engineering Research Center 2007). A second output of this paper is a map of the elements at risk (EaR) for the population and buildings of Istanbul, and the introduction of a new approach of net elements at risk (NEaR).

ABSTRACT The development of a general purpose disaster impact assessment software package is a daunting task, complicated by a number of technical, political, and administrative challenges. For example, geospatial information management should account for the administrative system of the country subject to the assessment, while the hazard, fragility, and inventory each have features that require implementation and display decisions that are consistent with the region. To accommodate the requirement of Istanbul, as possibly the largest megacity in the world with an acute earthquake risk problem, a new software package was developed, based on the Mid-America Earthquake Center platform MAEviz. MAEviz-Istanbul, the first stage of HAZTURK, is described in this article with emphasis on the regional significance and consistency of the development from an earthquake engineering viewpoint. Sample analyses are also provided at the end of the article to demonstrate the potential use of such a tool in assessing the impact of earthquakes on a densely populated cosmopolitan region.
