中文摘要 | 一九九六年,賀伯颱風侵襲臺灣,並從本島西北方通過。從歷史觀點來看,颱風由此路徑登陸通常都會造成比其他路徑更大的災害。賀伯颱風所挾帶豪雨是破記錄的,尤其是在中部,而這樣的豪雨共造成了超過1315處山崩及20處土石流、73人失蹤、463人受傷,財產損失大約十億美元。 此篇研究顯示了賀伯颱風及所造成災害不同特性,包括它們的大小及自然發生的週期,而在臺灣中部是很少有如此災害發生的,所以也一併探討了地質、地形及工程方面之肇因。另外,與其他國家災害相較,結果顯示,當豪雨碰到地形有斷層存在時,通常是造成重大災害之主因。 |
英文摘要 | In 1996, Typhoon Herb devastated Taiwan, moving across the northwestern part of the island. Hisotrically, typhoons traveling such a route have frequently caused worse damage than typhoons on other routes. Herb brought record-breaking precipitation to Taiwan, especially the central part of the island. The heavy rainfall led to more than 1315 landsides and 20 debris flows. Seventy-three lives were lost, 463 persons were wounded, and property losses of about 1 billions USD were sustained. This study present the distinct characteristics of Typhoon Herb as well as the induced hazards, including their extraordinary size and recurrent nature. The focus is on central Taiwan, where the severest hazards were encountered. Furthermore, the geological, geomorphologic and engineering factors, which may have magnified the consequences of the hazards, are also discussed. A comparison of hazards in other countries is also made and the results indicate that the extremely heavy rainfall encountered as well as the existence of a boundary fault in the study area are the most susceptible factors inducing the extraordinary hazards. |
