Use of near-field seismograms makes it possible to represent the rupture process of a target earthquake indetail. Nevertheless, few sets of strong motion data have been obtained in fault regions yet. This paper describes the observations of strong ground motions of some earthquakes occurring in the recent 20 years and reviews the results of the analyses of these data in the context of strong motion seismology. Some new aspects of observing and analyzing strong motions are discussed for seismology and engineering seismology in the next decade.
