Accelerograms recorded at Caltech during the Whittier Narrows earthquakes of October 1 and 4, 1987 : a preliminary report

Accelerogram records were recovered from 12 stations of the California Institute of Technology strong-motion array following the Whittier Narrows earthquake of October 1, 1987 and its major aftershock on October 4, 1987. This report presents the unprocessed accelerograms as well as the seismological characteristics of these two events. The locations of the Caltech strong-motion stations are described in detail, and some preliminary results are deduced from the accelerograms. The damage produced in the Los Angeles area is also briefly described.
