Alquist-Priolo Earthquake Fault Zoning Act (1972) and the Seismic Hazards Mapping Act (1990) direct the State Geologist to delineate regulatory "Zones of Required Investigation" to reduce the threat to public health and safety and to minimize the loss of life and property posed by earthquake-triggered ground failures. Cities and counties affected by the zones must regulate certain development "projects" within them. These Acts also require sellers of real property (and their agents) within a mapped hazard zone to disclose at the time of sale that the property lies within such a zone. NOTE: Fault Evaluation Reports are available for those areas covered by a Regulatory Map however there are reports available for areas outside the Regulatory map boundary. For a complete set of maps available for purchase on CD please contact the CGS Library.

Since the 1960's, the California Geological Survey (CGS) has produced numerous maps that show landslide features and delineate potential slope-stability problem areas. Preparation of these maps has been episodic, often driven by landslide disasters and subsequent legislative mandates. Many CGS landslide maps and related products have been produced for local or state agencies in response to their specific needs. This index includes landslide maps produced over many years and for a variety of purposes. See the description of CGS landslide programs for details of some of the major programs and types of landslides and landslide maps. Landslide reports and maps for the California Geological Survey's Information Warehouse.

In summer 2021, the Bureau of Land Management - Nevada (BLM NV) requested that the U.S. Geological Survey Mineral Resources Program (USGS MRP), acting through the Geology, Minerals, Energy, and Geophysics Science Center (GMEGSC) and other collaborating USGS Science Centers, conduct a scoping study to: 1) discover mineral resource data and relevant publications that have been released since the publication of the 2016 USGS Sagebrush Focal Area Mineral Resource Assessment (SaMiRA; Day and others, 2016) for the Nevada portion of the Focal Area, and 2) evaluate whether these data support an update to the assessment for the SFA lands in Nevada. The commodities of interest for this scoping study are: copper, gold, lead, lithium, molybdenum, silver, tungsten, vanadium, zinc, and rare earth elements (REEs). This report is being released as a restricted file federal interagency report (RFFIR). This data release comprises the geospatial files used in the post-2016 assessment. It includes a point shapefile of exploration sites (SaMiRAII_exploration_sites.shp), a point shapefile of reanalyzed NURE geochemical data (SaMiRAII_NURE_reanalyzed.shp), four polygon shapefiles of mine claims and plans and notices for the purpose of plotting density (SaMiRAII_mill_sites_counts.shp, SaMiRAII_placer_claims_counts.shp, SaMiRAII_plans_notices_counts.shp, SaMiRAII_lode_claims_counts.shp), a polygon shapefile of mine claims (SaMiRAII_mine_claims.shp), and a polygon shapefile of plans and notices (SaMiRAII_plans_notices.shp). The SaMiRAII_mine_claims.shp and SaMiRAII_plans_notices.shp shapefiles contain overlapping polygons due to the fact that multiple claims can reside in a single section or quarter section.
