Abstract : Seismic research efforts covering four general areas are outlined. These studies deal with (1) the structure and inhomogeneities of the earth's interior, (2) source mechanisms of earthquakes, (3) seismic arrays, frequency-wavenumber studies of microseisms and discrete formulations of wave propagation in layered media, and (4) design and construction of a stable long-period mercury tiltmeter.
