This report presents the strong-motion earthquake records of the 1983 Nipponkaichubu earthquake in port areas in Japan.
　Event data of earthquake are listed with the maximum component accelrations of all the records obtained in the network of the Port and Harbour Research Institut
e. 11 records of them are presented as acceleration time histories, integrated velcities and displacements, response spectra, Fourier spectra and loci of acceleration and displacement. Listings of the digitized record are presented for six records. This report has almost the same procedures for data processing as the preceding annual reports.
