Abstract/Summary:
This study focused on collection and analysis of geologic and seismic data for determination of the potential hazards resulting from earthquakes and landslides in Scotts Valley, Santa Cruz County, California. A series of maps were developed at a scale of 1:12,000 depicting engineering geology, landslide occurrence, landslide potential, and liquefaction potential.;Seismic records suggest that an earthquake equalling or exceeding 7.0 Richter magnitude has a recurrence interval of 100 years. The greatest seismic hazard is believed to be maximum earthquakes on either the San Andreas fault (8.5 RM) or Zayante fault (7.4 RM). The late Holocene alluvial deposits exhibit a high to moderate liquefaction potential.;Landslides are one of the primary geologic processes in the study area and pose a significant geologic hazard. The landslide susceptibility map divides the area into areas of high, moderate, and low landslide potential.
