This preliminary report summarizes California Division of Mines and Geology (CDMG), Strong Motion Instrumentation Program (SMIP) accelerograph records recovered from the 25 through 27 May 1980 Mammoth Lakes area earthquake sequence. All CDMG accelerograph stations that were "triggered" (activated) by one or more of the earthquakes are mapped in Figures 1 and 2, and listed in Table 1. These stations, with their respective ground accelerations and other pertinent data, are arranged in Table 2 in order of increasing distance from the epicentral area.
