Abstract
This report provides strong-motion users with information recovered by the Seismic Engineering Branch of the U.S. Geological Survey. The document contains recent accelerograph records, preliminary reports on the southern California earthquake of January 1, 1976, and the Guatemala earthquake of February 4, 1976. Several abstracts and information on the availability of digitized data are presented. A summary of the records obtained during the period of January through March includes maximum accelerations, S-wave minus trigger times, and time durations for which the acceleration level exceeded 0.10 g. A set of figures indicate station locations in the vicinity of the January 1 earthquake, locations of the Guatemala earthquake and aftershocks, the seismogram from the Guatemala earthquake, and the accelerogram from the February 18 Guatemala aftershock.
