摘要

The report presents documentation for the development of seismicity parameters tobe used as input for probabilistic seismic hazard analyses at the Savannah River Site in South Carolina. The hazard analysis is to be conducted by personnel at the Lawrence Livermore National Laboratory and the author was one of several seismicity experts providing the requisite seismicity parameters of seismic zonation, magnitude recurrence relations, focal depth distributions, and maximum magnitude estimates. The spatial distribution of historical seismicity is given primary emphasis in the definition of zonal boundaries. Maximum magnitude estimates are derived from a combination of the magnitude of the 1000-year earthquake, the historical maximum earthquake plus one magnitude unit, and the values calculated using various published relationships between magnitude and fault plane area.
