    Abstract: 本研究利用MATLAB軟體及李顯智博士所開發之程式ASICAE進行分析,程式將符合設定的時間週期和空間範圍之地震事件顯示於台灣和附近海域的圖面上,透過程式篩選出地震圓弧交叉,此交叉必須為完全雙交叉,並在地震弧交叉出現的後一天進行驗證,以確保此交叉為「最強地震圓弧雙交叉」。
    本研究資料來源為台灣中央氣象局地震資料庫,擷取西元1977年至2016年之地震目錄,以距地表深度70公里以內之地震繪製地震分布圖,分別以2年、3年、4年及5年之週期(dy)搜尋最強地震圓弧雙交叉,分析其交叉點半徑90公里範圍內後續發生芮氏規模5.7以上強震之可能性,再將後續強震與最強地震圓弧雙交叉間隔之時間(dt)列表紀錄,並觀察不同搜尋週期對台灣地區最強地震圓弧雙交叉之影響。。
    目的為分析不同的搜尋週期是否會影響成功預測強震之機率,並找出最適合之搜尋週期以提升預測準確值,得以實際應用於防災上。
    ;This research uses ASICAE which developed by H.C.Lei to select an appropriate minimum magnitude of seismic enents to display the coordinates of the seismic events on the Taiwan map by MATLAB. And then we try to find the strongest intersection of the circular arcs of earthquakes.
    The data source is provided by the seismic database of the Central Weather Bureau of Taiwan. We extracted the earthquake catalog from 1977 to 2016 for analysis. This research changes the values of the parameters of dy in order to analyze the impact of dy on the strongest intersection of circular arcs of earthquakes.
    The purpose of this analysis is to find the most appropriate value of dy to improve the accuracy of prediction.
