Research Directed Toward the Use of Long and Intermediate Period Seismic Waves for the Identification of Seismic Sources

Abstract

Seismological research supported by Air Force contract F19628-71-C-0245 at the Lamont-Doherty Geological Observatory is summarized for the period 1 July 1971 to 31 December 1971. During this period extensive analysis was done on the systematic regional variations in stresses. High stress earthquakes that usually exhibit anomalously large high-frequency content are the most likely ones to be confused with explosion signals. Higher stresses are expected to be accumulated in regions where new faults are being created in competent rocks. A possible temporal change of travel time is observed at some of the stations in western United States.
