Amplitude and propagation characteristics of short-period seismic surface waves in Las Vegas Valley
Technical Report
·
OSTI ID:4353278
An investigation was conducted to assess the possibility that local geologic structure cortrols surface-wave amplitudes and dispersion from underground nuclear explosions recorded in the Las Vegas Valley. Rayleigh-wave group velocities are determined at several stations for the underground nuclear explosion Carpetbag. The observed group-velocity dispersion can be satisfied by an average Las Vegas Valley structural model consisting of a low-velocity alluvium layer 0.9 kilometers thick overlying an existing model based on a refraction survey for the area. The model agrees satisfactorily with the known geology of the valley. (TFD)
