This paper discusses the evolution of dynamic analysis in geotechnical earthquake engineering from the 1960s to the present. One of the most significant events which contributed to the rapid development of geotechnical earthquake engineering in the 1960s was the application of finite element methods to the analysis of embankment dams for the first time by Clough and Chopra (1966). A major improvement in analysis occurred in 1972 when Seed and his colleagues at the University of California in Berkeley developed the equivalent linear method of analysis for approximating nonlinear behavior. While this program development was going on, the capability of testing soils under cyclic loading was also being developed. Therefore by 1975 geotechnical engineers had many of the analytical and laboratory capabilities necessary for realistic assessments of the seismic response of soil structures. The late 1970s and the 1980s saw the development of nonlinear dynamic effective stress analysis.
