1 地震危险性评定历史越南1924年开始从事地震研究,由富连研究所地震台(法国支持参与)承担。1968年编制了南越地震区划图.1985年,NCSR地球物理研究所编制了第一张1:200万越南全国综合性地震危险性评估图。其成果已发表并作为工业设计中的工程场地评定和生命线研究的基础资料。1987年以来,越南国内由于水电站的增加,地震危险性评定成为一个很重要的问题。地震台的数量已经由1957年的2个增至1980年的6个,到1992年已猛增到19个。
1 History of Seismic Hazard Assessment Vietnam started seismic research in 1924 and was undertaken by Seismological Station of Fu Lian Institute (with the support of France). The South Vietnam Earthquake zoning map was prepared in 1968. In 1985, NCSR Institute of Geophysics compiled the first 1: 2 million nationwide comprehensive seismic hazard assessment of Vietnam. The results have been published and used as a basis for industrial site design assessment and life line research. Since 1987, due to the increase of hydropower stations in Vietnam, the seismic hazard assessment has become a very important issue. The number of seismic stations has risen from 2 in 1957 to 6 in 1980, and by 1992 it had soared to 19.
