Requirement Analysis for Determining Hazard and Vulnerability in Multiple Disaster Risk Management

Abstract

Disasters cause great disruption for human, environment and assets. To mitigate or reduce the impact of disasters; hazard, vulnerability, and risk analysis are performed within the risk management activities. Disaster management generally occurs in four successive stages. Damage mitigation and preparedness stages for pre-disaster, response and recovery stages for post-disaster interact with one another. Success in disaster management depends on successfully realization of the activities that are performed in the disaster cycle. Disaster risk management contains activities such as hazard, vulnerability, risk assessment, and analysis. Disaster hazard is a natural or human originated event; vulnerability is the features and situations of a society that cause exposure to the harming impacts of a hazard event. The composition of the disaster hazard and vulnerability expose the risk of disaster. Some disaster hazard such as following the earthquake landslide, floods, and fire can occur together and can trigger each other. Similarly more than one disaster can be seen together and that exposes the multi-hazard risk situations. In order to manage the disaster risks data requirement, hazard and vulnerability analysis must be performed first. Also an integrated approach is required for disaster. For this purpose, in this study data requirement analysis was performed for the analysis of very common disasters in Turkey such as landslides, fire, forest fire, flood and earthquake.
