| 摘 要： | 2010年2月27日南美洲智利中部近岸发生强震并引发海啸.利用海啸期间台湾周边海域验潮站的潮位资料,分析了此次海啸对台湾周边海域的影响,海啸波通过太平洋于震后25.5h到达台湾周边海域,最大波高达44 cm.进而从理论上讨论了海啸传播时间和波高变化的简单计算方法,并引入了波高衰减因子.结果表明,该简单计算方法能快速且较准确地计算出海啸波的传播时间,引入的波高衰减因子,可在一定程度上为台湾周边海域海啸的方便快捷的预警提供参考.

| Abstract: | A great earthquake occurred off the central coast of Chile,South America,on February 27,2010,and produced tsunami.The data recorded by tide gauges surrounding Taiwan were analyzed in the study.After 25.5 hours of the earthquake,the tsunami wave arrived at tide gauges through the Pacific Ocean,and the maximum wave height recorded was 44 cm.Then a theoretical method was discussed to calculate the tsunami wave propagation time,otherwise wave height attenuation factor was used to measure the wave height.The results showed that the theoretical method could calculate the propagation time quickly and accurately,and the wave height attenuation factor provides a convenient and efficient reference on tsunami warning for seas surrounding Taiwan. |
