This report describes a study in which group velocity dispersion was determined for short-period Rayleigh waves recorded from blasts detonated at the San-Vel quarry in Littleton, MA. Field data were recorded to complement network data in order to create a denser distribution of stations than was possible in past experiments. Group velocity dispersion was estimated for each path. The resulting dispersion curves were analyzed to investigate the relationship between group ...

This report describes the results of five research projects that cover a range of topics related to seismology in general and to nuclear test monitoring in particular. Details of the results of each project are described in the following five Scientific Reports: (1) Database Relations for Seismic Phases Reported by Stations in the Former Soviet Union; (2) Site Effects on Regional Seismograms Recorded in the Vicinity of Weston Observatory; (3) ...
