During the past three years, nine visiting seismologists from Japan, England and Denmark have participated in a program of research at Lamont. During their stay here, they worked either jointly with the Lamont seismology staff or individually on many important problems, some of which which directly bear on the detection of explosions and earthquakes and some of which are fundamental enough to offer wide application to the basic understanding of the earth's crust, the mantle and the core, and the earth as a whole. As a result of their research, we have made progress in earthquake prediction--considering earthquakes as statistical events in a stochastic process; we have a more detailed understanding of the travel times of body waves through North American for both nuclear explosions and earthquakes; we have extended the theoretical investigation of wave propagation through complicated structures, such as a corrugated interface and a medium with a hyperbolic type of interface; and we have a detailed understanding of the dissipation factor 1/Q both in the upper and the lower mantle and in the core. These findings are closely related to the problems of location of seismic events and of differentiation of explosions from earthquakes. /Author/
