Geologic description of selected strong-motion accelerograph sites, Part II

One of the major tasks of the U.S. Geological Survey as regards seismic engineering is the collection and dissemination of strong-motion accelerograph records. When analyzing these records certain information describing the instrument site is important: local geology; instrument housing (buildings, dams, bridges, instrument shelters, etc.); local topography; and proximity of an accelerograph to man-made structures that might influence the record. This report describes local geologic conditions of selected sites and is the second in a series of continuing reports covering strong-motion accelerograph sites in the western hemisphere. See Open File Report 78-1005 for part one.
