A series of review articles on engineering seismology will be published in this and following volumes. This is a brief review to outline a 40-year progress of studies in the field of engineering seismology in Japan.
The first stage of engineering seismology in Japan is represented by the development and installation of SMAC-type strong motion accelerograph, Kawasumi's map and Kanai's empirical formula for estimating strong ground motion.
During a decade of 1960, some significant strong motion records were obtained and an idea on site amplification of earthquake ground motion due to S-wave multiple-reflection came to a common understanding with a help of S-wave velocity measurement in the soft ground.
The topics of a decade of 1970 are that a dislocation source model was brought in the field of engineering seismology and the period range of earthquake ground motion in the field of engineering seismology was extend from 1s to longer period than 10s.
Predictions of earthquake ground motion taking into a complex rupture process and irregular ground structures came to a major target since 1980.
