Abstract: In this paper a description is made on the measure of tsunami magnitude, which must include the size of tsunami source, and a direct relation of tsunami magnitude at itc source with the extent and pattern of crustal deformation. In correlation betweem tsunami and earthquake, except the earthquake magnitude, the seismic source fracture pattern is emphasized. Here we also discuss the processing and analysis of historic marine earthquake data, prediction of potential tsunami sources, investigation of tsunami propagation path, and comprechensive evaluation in the process of safety evaluation of nuclear power plant site.

Key words: Tsunami, Nuclear power plant siting, Safety evaluation, Crustal deformation

摘要： 海啸大小的量度应包括关于海啸"源"处大小的描述,"源"处海啸的大小与地壳形变规模和方式有着直接的关系。在海啸与地震的关系中,除了地震震级外,强调了震源破裂方式这一因素。阐述了关于核电厂选址安全评价中历史资料的整理、分析,对未来海啸"源"的预测、海啸传播路径的调查和分析以及综合评价等4个方面进行了讨论。
