台灣位於環太平洋地震帶,地震頻繁仍是台灣無法避免的,地震災害至今仍屬於不可預測之天然災害,因此導致地震發生後所造成人員與財產的損失及傷亡是無法準確預測的。地震規模大小、震源深淺及發生的位置將影響其造成之損失以及傷亡。都市為一個人口密集、建物林立、經濟活躍處,若地震發生於都市時,所造成之損害將遠超過其他地區,因此都市的地震防災需要特別的規劃。 本研究針對台北都會區地震減災與「台灣地震損失評估系統-TELES」的結合,以風險管理的角度研擬都市風險分析之架構,並利用風險分析配合都會區之自然環境與人文活動,萃取都會區的風險因子,其中針對所提出之風險因子說明其各自之屬性、可及性以及資料精度,並探討風險因子與TELES系統相互之關係,由此探討減災手段的落實。本研究所提出之風險因子可提供災損地圖之架構更加完善,並透過各項因子之探討,提供某地區了解其特性、損害、脆弱與防災能力。希望可各部會機關與民間業者,作為擬訂相關的耐震設計、都市規劃、地震保險與風險管理策略…等之參考依據。
Taiwan is located in the circum-Pacific seismic zone, and thus earthquakes are not avoidable. Until now earthquake are still unpredictable and the casualty and the loss of property caused by an earthquake can not be estimated accurately. The magnitude, the focal depth and the epicenter of an earthquake all have an influence on the casualty and the loss of property. Cities are the place where the population and the buildings are crowded and the economy is flourishing. If a major earthquake occurred in cities, the loss will be much more than occurred in other areas. Therefore, it needs for special planning for the urban earthquake disaster prevention. This study focuses on the combination of the earthquake disaster reduction in Taipei metropolitan area and the “Taiwan Earthquake Loss Estimation System(TELES)”, and imitates the risk analysis of urban structures through the point of view of risk management. By considering the risk analysis with the natural environments and human activities the risk factors of the metropolitan area were extracted. Furthermore, this study discussed in length the characteristics, accuracy and availability of these risk factors, and investigated the relationship between them and TELES. This study of risk factors can provide a better framework for risk maps and a better understanding for the characteristics, vulnerability and hazard resilience fot a specific region. Hope that this study can be helpful for the earthquake disaster mitigation planning, urban planning and risk management strategies for the public as well as private sectors.
