Strong-motion records were recovered from 101 stations of the California Strong Motion Instrumentation Program (CSMIP) following the Whittier earthquake of October 1, 1987 (also known as the Whittier Narrows earthquake). Sixty-three of those stations were ground-response stations. This report presents results of the digitization and processing performed on the records obtained from 36 of these stations. The remaining 27 stations typically had maximum accelerations of 5% g or less, as shown in the data report by Shakal et al. (1987), and those records were not digitized. The results for the digitization of records obtained at CSMIP structural-response stations are presented in an accompanying Part II report for buildings, and a Part I11 report covers for bridges and dams (Huang et al., 1989a and b).
