Description: Technical Report
From the Introduction: The purpose of this investigation is to define the maximum potential for earthquakes at Ririe Dam and to provide appropriate ground motions for earthquake shaking at the dam. These ground motions are for use in the design analysis of the present earth dam and associated structures. This investigation includes both a geological and seismological study and consists of the following parts: (a) an examination of the local and regional geology including an evaluation of active faulting, (b) a review of the historic seismicity of the area under study, and (c) the determination of the source and magnitude of maximum earthquake(s) that may affect the damsite and the attenuated peak ground motions that would be produced at the damsite.
