Geological-Seismological Evaluation of Earthquake Hazards at Hartwell and Clemson Upper and Lower Dams, South Carolina
Abstract
Seismic source zones have been developed for the southeastern United States that are based on the geology and historic seismicity. A floating earthquake was assigned to each source zone and earthquake motions were attenuated to Hartwell and Clemson Upper and Lower Dams. A maximum credible earthquake at each dam is a far field, MM VII (M = 5.5) earthquake. Horizontal ground motions for this earthquake are as follows: acceleration 190 cm/sec2, velocity 14 cm/sec, and duration 11 sec. Acceleration and response spectra appropriate to these values were selected and are included. Where vertical motions are considered, they may be taken at two-thirds of the horizontal. (SDW)
