RESEARCH IN SEISMOLOGY.

Abstract

Seismic research projects supported by the contract are summarized under three broad categories: The structure and some properties of the earth's mantle and deep interior are investigated using arrays and dt/d(delta) measurements, dense net of stations in North America, as well as seismic surface waves and free oscillations. Body and surface wave propagation in media with irregular interfaces is studied using numerical techniques. Magnitude discrepancies, focal depths, mechanisms and statistics of earthquake occurrences are discussed. (Author)
