IDENTIFICATION OF MULTIPLE RUPTURE PROCESS OF 1979 IMPERIAL VALLEY EARTHQUAKE BY NEAR-FIELD ACCELEROGRAMS

抄録（英）：
An analysis of identifying the multiple rupture process of the 1979 Imperial Valley, California earthquake is made using the 32 near-field accelerograms recorded during that earthquake. By careful visual looking, distinct phases in each accelerograms are identified. Next, the location of the source which generated such distinct phases in the accelerograms is determined using the S and P travel time curves. It is indicated that the earthquake is a multiple event with two or three smaller events in the period of less than 1 second and that the main energy is released from a localized area about three kilometers to south under the Meloland station. The results are not completely but fairly coincident with those obtained by Hartzell and Helmberger (1).
