This report provides strong-motion data users with information recovered by the Seismic Engineering Branch of the U.S. Geological Survey. It contains a summary of all accelerographs recovered from the National Strong-Motion Network during the period of July 1 through September 30, 1976. Reports on the use of strong-motion recurrence intervals in the design and planning of accelerograph networks and the current status of the strong-motion information retrieval system are presented, along with abstracts of recent reports, notes on numerous strong-motion information sources, and the availability of digitized data. Table 1 includes accelerograph records obtained between July and September showing station locations, maximum accelerations, S-wave minus trigger times, and time durations for which peaks of acceleration exceed 0.10 g. Table 2 lists recurrence times for stations in use over a thirty-year period, and Table 3 presents a summary of costs per record. A map of the United States indicates the number of events with an intensity of six or greater.
