Development of a Decision Support System for Earthquake Risk Assessment and Loss Mitigation: The Hanoi Case Study

要旨

A GIS-based Decision Support System ( DSS) was developed to assist users in managing earthquake risk for an urban area. The system consists of a spatial database and two main components. The first component is designed to assess the earthquake hazard caused by a predefined scenario earthquake for a chosen urban region and provides users with a set of ground shaking and ground failure maps. The second component is specialized on earthquake risk assessment, which resulting in a set of maps depicting level of damage and losses of various elements at risk within the community (people, buildings). The system's outputs, which are forecasts of damage and human impacts that may result from future earthquakes, can be used to manage effective earthquake disaster reduction measures including preparedness, emergency response activities and recovery actions and policies. As an illustration of the system, some results of the Hanoi case study are presented.
