因臺灣地區所在的位置、板塊分佈的關係導致臺灣地區地震頻繁。地震與斷層形態息息相關，故本文以現今已知的兩種指標「地震相對強度指標（RI）」與「地震加速度指標（AI）」，分析集集大地震前的RI 和AI於斷層裂縫末（尖）端之間的反應，以判斷往後地震發生的可能性，再調整公式中不同的參數，探討其對於指標的影響及穩定性，並以其他非斷層區域及其他地震作為對照組驗證。;There are many earthquakes in Taiwan and earthquakes are closely related to the activities of faults. We uses known two indexes, Relative Intensity（RI）and Acceleration Index（AI）, to analyze the behaviors of different faults in Taiwan before the Chi-Chi earthquake and study RI maps and AI-t graphs of these faults so as to judge the possibility of occurrence of big earthquake in the future. Furthermore, we study the parameters in the formulae to elaborate on the stability of RI and AI, we also analyze other earthquakes and other zones of faults to make comparisons.
