關鍵字詞：地震弧交叉、地震預測、大地震不發生之預測 ;During 2016 and 2017, Hin-Chi, Lee issued 5 essays about earthquake analysis which proposed the concept of the intersection of circular arcs of earthquakes.
The intersection of circular arcs of earthquakes can be seen as a indicator of interaction between two sets of stress concentration, and it becomes a useful tool of earthquake prediction. In addition, we can make use of the information of the previous intersection of circular arcs of earthquakes to analyze the probability of non-occurrence of strong earthquake, which is the subject of this thesis.
Key words: the intersection of circular arcs of earthquakes, earthquake prediction.
