Effects of local geology on ground motion in the San Francisco Bay region, California: A continued study Effects of local geology on ground motion in the San Francisco Bay region, California: A continued study
Measurements of ground motion generated by nuclear explosions in Nevada have been completed for 99 locations in the San Francisco Bay region, California. The seismograms, Fourier amplitude spectra, spectral amplification curves for the signal, and the Fourier amplitude spectra of the seismic noise are presented for 60 locations. Analog amplifications, based on the maximum signal...

Geodimeter measurements of slip and strain accumulation along the San Andreas fault Geodimeter measurements of slip and strain accumulation along the San Andreas fault
The U.S. Geological Survey conducts repeated geodimeter surveys of trilateration networks in central California in order to study the processes of slip and strain accumulation along the San Andreas fault. The precision of distance measurement is described by a standard deviation σ = (a2+ b2L2)12 where a = (a2+ b2L2)12 where a = 3mm, b = 2 · 10−7, and L is the line length. Within the...
