On April 3, 2024, a magnitude 6.6 earthquake struck offshore Hualien County in Taiwan, with a shallow focal depth of approximately 10 kilometers. Due to the high magnitude and proximity—only about 200 kilometers from the Fujian coast—residents in multiple cities across Fujian Province, including Fuzhou, Xiamen, and Quanzhou, reported noticeable shaking.There are three main reasons why the tremors were so distinctly felt in Fujian: First, the earthquake was both strong and shallow, allowing seismic energy to transmit efficiently over distance. Second, Taiwan and Fujian lie along the tectonic boundary between the Eurasian Plate and the Philippine Sea Plate, sharing a geologically continuous crust that minimizes energy loss as seismic waves travel. Third, much of coastal Fujian consists of alluvial plains and soft soil layers, which tend to amplify ground motion during earthquakes.Experts noted that while this quake caused no major damage in Fujian, it serves as a reminder for coastal communities to enhance earthquake preparedness and become familiar with emergency response procedures. It also underscores the importance of strengthening regional seismic monitoring and early warning systems.
2024年4月3日，台湾花莲县海域发生6.6级地震，震源深度约10公里，属于浅源地震。由于震中距离福建沿海仅约200公里，且地震能量释放较大，因此福建多地如福州、厦门、泉州等地均有明显震感。福建之所以震感明显，主要有三个原因：一是地震震级高、震源浅，能量传播效率高；二是台湾与福建同处欧亚板块与菲律宾海板块交界带，地壳结构连续，地震波传播损耗小；三是福建沿海地区多为冲积平原和软土层，对地震波有放大效应，进一步增强了震感。专家指出，虽然此次地震未对福建造成严重破坏，但提醒沿海居民应提高防震减灾意识，熟悉应急避险措施。同时，地震也再次凸显了加强区域地震监测与预警系统建设的重要性。
