Earthquake Hazards 25 Years After Chi-Chi: Learning from the Past to Prepare for the Future

1999年9月21日發生的Mw 7.6集集地震為台灣近代史上最具破壞性的烈震，除了地表破壞之外，還誘發大量餘震和山崩，不僅在台灣地震觀測史上極具科學價值，亦對台灣災防體系有著深遠的影響。集集地震為科學界提供了斷層帶上難得的觀測數據，從地形變、強地動到地質鑽探，深入探究地震破裂的過程，而集集地震所產生的嚴重災損，促使我們重視地震危害並加強防震規範。時隔25年，儘管台灣在建築法規、地震預警及危害評估等防災減災措施上已有長足進步，但強震威脅依然存在。

本專刊收錄12篇研究論文（https://pubs.geoscienceworld.org/bssa/issue#58508-723274），立基於集集地震的教訓，進一步探討近年來的重大地震事件、活動構造與災防進展。其中，2024年Mw 7.4花蓮近海地震展現了複雜的共軛斷層系統與餘震演化，其地動特徵與1986年Mw 7.3地震極為類似，而2022年關山—池上地震序列則揭示了縱谷內斷層交互作用的最新證據。此外，新研究亦重新審視了台灣西部的地殼滑脫帶構造（如2010年甲仙與2016年美濃地震）。除了陸域斷層，周遭海域活動構造的地震機率圖首次於本刊發表，為台灣地震災害風險評估的重要里程碑。在災害管理上，迅速將地震科學資訊運用於救災預估，強化社群鏈結，都有助於提升台灣的社會應變與韌性，實現「從過去學習，為未來準備」的核心精神。
