During the course of the year the principal technical accomplishments have included efforts in the following areas the focal mechanism of earthquakes, model studies of explosion generated waves, azimuthal departure of P wave motion from the great circle path, determination of the depth of focus, and the phase velocity of surface waves. Each of these studies is reported. Other supporting work, not reported in the present work, has been the operation of a quadrilateral long-period seismic array and the installation of a small aperture, three element, bore-hole seismometer array in southeast Missouri.
