| dc.description.abstract | 本研究透過電腦程式將地震目錄中規模4.6級以上之地震事件篩選出來，繪製出地震事件分佈圖，並利用應力集中效應的概念，尋找圖中的地震圓弧，再針對地震圓弧交會的應力集中相互作用區作統計與分析。
結合應力集中效應的概念，以及岩石中張力裂縫的排列型式，發展出了地震圓弧交叉分析方法，我們對其排列模式、長度、包含之事件數目、各事件間距均做了規範，也對各事件發生位置設定了容許的偏差值，目的是為了讓繪製地震圓弧時有一致的判斷依據。
本研究選取過去地震目錄中2003年至2013年間之地震事件作分析，過程中發現了33個地震圓弧交叉案例，其中有28個案例在後續3年期間，距離交叉點70公里內，有至少一個規模5.8級以上之強烈地震發生，讓我們更加確定地震圓弧交叉現象與強烈地震之間的關聯性。 | zh_TW |

We select the earthquake events with magnitude over 4.6 in earthquake catalog by the computer program, and plot the earthquake events on a figure. Then, we use the concept of the circular arcs of earthquakes to find out the locations of stress localization, and study the areas subjected to the localized stress interactions represented by the circular arcs of earthquakes. This research try to analyze these phenomena by statistics.
Combining the concept of stress localization and the alignment of tension cracks in rocks, the analysis method of circular arcs of the earthquakes is developed. We standardize the alignment pattern, the length, the number of events included and the distance between the events, also we set the tolerance to the position of the events so as to have the same basis to draw the circular arcs of earthquakes.
In this research, the earthquake events with magnitude greater than 4.6 from 2003 to 2013 in the earthquake catalog were analyzed, and 33 intersections of the circular arcs of earthquakes were found. Among these, 28 cases were found to have at least one event with the magnitude over 5.8 occurred within 3 years near to (within 70 km) the intersection points. This result makes us more confident about the correlation between the circular arcs of earthquakes and the strong earthquake events. | en_US |
