本研究利用不同的搜尋週期來搜尋極淺層最強地震圓弧雙交叉，並經過幾何性質的篩選，以進行台灣本島及附近規模5.7以上之短期強震機率分析。 研究結果顯示，最強地震圓弧雙凸交叉整合不同搜尋週期並以幾何性質篩選之結果，本理論140天內強震預測命中率為67.9%(19/28);最強地震圓弧凹凸交叉整合不同搜尋週期結果，本理論140天內強震預測命中率為61.9%(26/42);最強地震圓弧雙交叉整合不同搜尋週期結果，本理論140天內強震預測命中率為64.3%(45/70)。 ;In this study, we utilize different shallow-depth double-intersections search periods for the strongest seismic arcs. By applying geometric filtering, we analyze short-term earthquake probabilities for Taiwan and nearby regions with magnitudes of 5.7 or higher. The research results indicate the following hit rates within 140 days: 1.For the Strongest Double-Convex intersection of CAE integrated search period, the prediction hit rate within 140 days is 67.9% (19/28). 2.For the Strongest Concave-Convex intersection of CAE integrated search period, the prediction hit rate within 140 days is 61.9% (26/42). 3.For the Strongest Double Intersection of CAE integrated search period, the prediction hit rate within 140 days is 64.3% (45/70).
