| dc.description.abstract | 本研究認為地震圓弧之交叉可視為地殼的中兩個應力集中區域交互作用之投射結果，利用MATLAB軟體的輔助，將地震事件之座標顯示於台灣圖面上，選擇合適的地震事件規模最小值，透過觀察地震分佈情形，找出近似均勻排列之5個的地震事件，繪出地震圓弧，若完成不了兩條弧線的交叉則將顯示規模下修，直至一個完整的地震圓弧交叉出現為止，即為最強地震圓弧交叉，地震圓弧交叉依交叉型態可分為單交叉及雙交叉。
本論文研究台灣地區從1976年1月到1989年12月間，距離地表深度30公里內的極淺層地震，針對最強地震圓弧交叉，分析其交叉點半徑70公里及半徑90公里範圍內，區域後續發生芮氏規模大於5.7及6.0以上強烈地震活動之可能性，再將後續地震活動與最強地震圓弧交叉間隔之時間與距離列表統計。如果在繪製過程中有地震圓弧交叉產生，但後續並沒有強震事件發生，也需要對這些情況做統計，且做合理之推測與解釋。
目的為研究此時間區間台灣本島及周圍海域的最強地震圓弧交叉與附近強震之時間和空間關聯，希望能輔助當前之地震預測技術，以達到較準確預測的目標。

| dc.description.abstract | This research thinks that the intersection of arcs of earthquskes can be taken as the result of the interaction of two stress concentration regions in the crust. We select an appropriate minimum magnitude of seismic events to display the coordinates of the seismic events on the Taiwan map by MATLAB. And then we try to find the strongest intersection of circular arcs of earthquakes from the points on the map. If no intersection can be found, the magnitude will be reduced until we find the strongest intersection of circular arcs of earthquakes (SICAE). According to the pattern of the intersection, it can be divided into the strongest single intersection of circular arcs of earthquakes (SSICAE) and the strongest double intersection of circular arcs of earthquakes (SDICAE).
SICAE can be regarded as the indicators of the intersections of two systems of stress concentration of the crust. The time range of the seismic events considered in this thesis is from June 1976 to December 1989. The SICAEs will be analyzed individually according to the type, uniformity and the sum of the released energy of the key events of each intersection. The purpose of this analysis is to study the temporal and spatial correlations between the SICAE around Taiwan and the strong earthquakes nearby.
