This document apprises strong-motion data users of available current data recovered by the Seismic Engineering Branch of the U.S. Geological Survey (USGS). Included is a summary of accelerograms recovered from the USGS's National Strong Motion Network during the period January 1 through April 30, 1979. Also described is strong-motion instrumentation in Imperial Valley, California. The seismicity of this region has been characterized by both earthquake swarms as well as mainshock-aftershock activity. Summaries of recent reports include information on earthquakes at Milford Sound, New Zealand; Santa Barbara, California; Bishop, California; St. Elias, Alaska; and Monte Negro, Yugoslavia. The availability of strong-motion information data reports, digitalized data, and additional information pertinent to USGS and other strong-motion programs is presented. The data summary includes accelerograms arranged chronologically as well as selected accelerograms from Imperial Valley. Maps identify accelerograph stations in Alaska and Imperial Valley.
