摘　　要：台湾海峡及其邻区,历史上曾发生过多次海水暴涨。在剔除那些因台风暴雨而引起的海水暴涨外,本区自公元647年以来共发生9次,本文按其形成把它划分为地震海啸和地震海溢两种类型,通过对地质构造、震源机制和地球物理资料等方面阐述其成因条件。认为地震海啸可分布在台湾海峡内,而地震海啸只能分布在台湾东北部海域;在地震海溢中,震级(M)和它影响的距离(△)关系为:M=5.892+0.019△。In the history sudden rises of th sea happened many times in the Taiwan Strait and adjacent regions. Nine seaquake and sea overflow, which are not caused by typhoon or heavy rain, have happened in this region since 647 A. D. .This paper makes an analysis of the conditions and causes and formation of the types of seaquake and sea overflow through the studies of geological structure, focal mechanism solutions and geophysical data etc. . it is concluded the sea overflow occurs only inside Taiwan Strait and seaquake only occurs in area northeast area of Taiwan. The relationship of magnitude (M) and the affecting distance (△) of seaquake is M=5.892+0.019△
