摘要
我国面临着来自于马尼拉海沟、台湾岛以及琉球海沟等海域可能形成的局地和区域海啸风险,及时、准确地预警海啸是一个难题。2004年印度洋海啸之后,基于海量数据库和GIS技术,国家海洋环境预报中心开发了南海定量海啸预警系统,可以对潜在海啸进行快速定量化的预警,并利用GIS软件进行预警结果可视化。利用该系统对2006年台湾南部地震海啸进行模拟预报,预报结果与实测结果基本吻合。
The main tsunami risk for China comes from Manila Trench, Taiwan Island and Ryukyu Trench, which may generate local and regional tsunamis. It is very difficult to forecast tsunami timely and accurately, because tsunami generates suddenly and propagates quickly. After the 2004 Indian Ocean tsunami, National Marine Environmental Forecasting Center(NMEFC) develops SCS quantitative tsunami warning system with massive database and GIS technology. Quantitative tsunami warning products could be produced quickly by the system,and visualized with GIS. Hind-cast results of 26 thDec 2006 Taiwan tsunami from the system show a good agreement with measurements in coastal tide gauges.
