綜合性地震脆弱度與風險評估：以新竹市為例

A Comprehensive Assessment of the Earthquake Vulnerability and Risk: A Case Study of the Hsinchu City

本文結合整體性地震風險評估與地方災害評估模型，進行都市層級的綜合性地震風險評估。此方法是以多元性概念，從事跨空間單元地震脆弱度與風險評估，以利於進行不同地理單元的地震脆弱度與風險比較分析，及助於暸解影響地震脆弱度與風險的主要因素。透過地震脆弱度指數與地震風險指數的估計，發現新竹市最高地震脆弱度與風險地區，集中在東區、東南與部分市中心區。此結果可提供土地使用與建築管理決策者，瞭解迫切需要進行減災的地區。

A novel method of incorporating holistic earthquake risk evaluation with hazard-of-place model was applied to assess the comprehensive earthquake vulnerability and risk at an urban-level. This method involves a multidimensional concept that is not only useful to identify and to demonstrate the spatial variability in earthquake vulnerability and risk, but also helps to understand the range in the underlying causes of that vulnerability and risk. By mapping the earthquake vulnerability and earthquake risk index, it shows that the relatively higher earthquake vulnerability and risk areas are located in the east, southeast parts of and a portion of central business district of Hsinchu City. The findings can assist the decision making process of land-use planning and judge where the mitigation efforts most required.
