中國大陸位於歐亞大陸板塊，東南部受到菲律賓板塊與太平洋板塊影響、西南部受到印澳板塊擠壓，以致地震發生頻繁且規模甚大，往往造成人員的傷亡、建物的倒塌等衝擊，因此若能掌握各個地方的危害程度，便能做出適當的風險管理。 地震危害度分析是在評估某次地震發生後，或不同回歸期下在各個地方可能造成多大的地震危害，本研究主要是將地震風險評估模型與編制第五代地震動參數區劃圖時所採取的CPSHA 理論結合，模擬出1998 年張北地震、1976 年唐山大地震與全中國大陸回歸期475 年的地震危害度分布圖，後續應用上可以作為救災、耐震設計、結構物補強的參考，亦能進一步分析出對不同標的物所造成的損害情形與損失金額，作為災害準備金的編列或保費釐訂的依據等用途。;Mainland China is located on the Eurasian Continental Plate. The southeastern area is affected by the Philippine Plate and the Pacific Plate, the southwest is squeezed by Indo-Australian Plate, so that earthquakes occur frequently, and the magnitude is usually large enough to cause many casualties, and make building collapse. Therefore, if we are able to grasp the hazard of every place, we can do the risk management effectively. Seismic Hazard Analysis is a method which can evaluate earthquake hazard demand for different return periods. In this study, we combine Seismic Risk Assessment Model with CPSHA to simulate the hazards distribution of 1998 Zhangbei earthquake, 1976 Tangshan earthquake and create the Hazard Map of 475 years return periods. Follow-up application, it not only can be used at disaster relief, seismatic design, structural reinforcement but also further analyze the damage and loss for different objects as the basis of budgeting disaster reserve fund or determining insurance premium and so on.
