Research on Multi Hazard Risk Management Framework for Coastal City
Coastal cities have to face many kinds of natural hazards, which always interact with each other, leading to many losses. And rapid development makes city system too complicated to manage for reducing casualties and economic loss. In order to solve the problems in multi hazard risk management of coastal cities, this paper attemptted to build a new framework based on historical data and hazard chain theory, and studied the disaster network with the center of typhoon and earthquake. The framework contains a four dimensional network composed of factor, hazard, event and vulnerability, and related by risk evaluation, chain probability and losses estimation models. The risk analysis for the network was proposed for estimate the influence over the city, aimed at more effective suggestions of planning and disaster reduction.
