Group: Summary
  These maps and databases provide a summary of the distribution of
  landslides evident in the landscape of the San Francisco Bay region.
  Original identification and map delineation of these landslides
  required detailed analysis of the topography by skilled geologists,
  a task generally accomplished through the study of aerial
  photographs. Such original landslide maps are now available for most
  of the region at scales of 1:24,000 - 1:62,500 (Pike, 1997).
  
  The distribution of landslides evident in the landscape -- most of
  which are slumps, translational slides, and earth flows -- is of
  interest both for evaluation of hazard and risk and for use in
  further study of landslides. Future movement of such landslides is
  most likely to occur within and around the places where they have
  previously occurred. A map showing the generalized distribution of
  these landslides was published by Nilsen and Wright for the 9-county
  San Francisco Bay region in 1979. Original sources available at the
  time of that compilation were incomplete for the region. Landslide
  mapping that has since become available provides a basis for
  revision and extension of that work, and modern procedures allow
  this to be done in digital form.
