第六章 結論與展望
6.2 未來展望
本研究中利用複數解載、波線追跡法，並且使用速度模型以及 Qp 三維衰減構造解算出不同地區震源 P 波加速度時間函數，對於不同分 區之加速度活動可分析出不同特性，然而震源加速度變化與臺灣地體 構造、地震活動度、震源發震形態、斷層錯動過程均有關(中央氣象局 地震測報中心, 2009)，因此未來對於不同孕震構造可以進一步以鑽井 或其他方式取得更精確的斷層錯動面樣本，藉此獲得更多震源錯動之 應力釋放過程資訊以比對本研究結果，如此將能對臺灣地區不同孕震 構造之斷層活動獲得更進一步的成果。
初達 P 波相較於 S 波與表面波之加速度振幅較小，因此過去研 究地震災害較少著墨於 P 波之影響。隨著地震預警的技術逐漸成熟以 及初達P 波波速相較於影響最大地表加速度(peak ground acceleration,
51
PGA)之主要波相 S 波與表面波快速之特性，未來若能藉由 P 波加速 度時間函數更加精確的分析結果，找出與S 波以及表面波之間的加速 度變化關係，則可由初達 P 波之特性計算出 S 波與表面波可能造成 PGA 大小，以提供地震預警更多參考資訊，為一未來值得研究之面 向。
另一方面，由地震紀錄解算出 P 波震源加速度時間函數後，未來 如能夠精確的由地震紀錄中分離出 S 波，則可利用 S 波之衰減因子 (Qs)進一步解算出震源 S 波加速度時間函數；解算出震源 S 波加速度 時間函數，配合精確之地下速度構造以及衰減構造，將能夠以之模擬 S 波於各地區造成的地表加速度變化。S 波為最大地表加速度之重要 影響因素，因此若能解算出精確的震源S 波加速度時間函數並且以之 模擬出S 波造成各地區之地表加速度變化，則在地震發生之前提供更 多資訊供相關領域參考，例如地震防災、減災規劃、地震學教育以及 各地區建築強度評估等將能夠提供更精確、更豐富的參考資料，亦是 未來地震學值得研究的方向之一。
