Tim McCrink Florante Perez 20170501 raster digital data US Geological Survey Scientific Investigation Report 2017-5013–A–H The Haywired Earthquake Scenario- Earthquake Hazards Menlo Park, CA US Geological Survey https://doi.org/10.5066/F7RN363Z https://doi.org/10.3133/sir20175013v1 This map shows the potential of widespread slope failures, in terms of landslide probability, triggered by a M7.0 scenario earthquake on the Hayward Fault in the 10-county area surrounding the San Francisco Bay region, California. The likelihood of landsliding was evaluated using an equation developed by Jibson and others (2000) that estimates landslide probability as a function of predicted Newmark displacement. Based on this equation, four landslide probability categories are established with their corresponding percent likelihood and displacement ranges: Low (0-2%; 0-1 cm), Moderate (2-15%; 1-5 cm), High (15-32%; 5-15 cm), and Very High (>32%; >15 cm).The seismic-landslide probability map covers the counties of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma. The slope failures are triggered by a hypothetical earthquake with a moment magnitude of 7.0 occurring on April 18, 2018, at 4:18 p.m. on the Hayward Fault in the east bay part of California’s San Francisco Bay region. This map shows the potential of widespread slope failures, in terms of landslide probability, triggered by a M7.0 scenario earthquake on the Hayward Fault in the 10-county area surrounding the San Francisco Bay region, California. The landslide probability and its companion dataset (landslide displacement) can be used to identify vulnerable highways and utility infrastructure and estimate economic loss to structures in developed areas of the San Francisco Bay region. 20170424 161800 20170516 161800 The 10-county area surrounding the San Francisco Bay region, California.

Users are advised to read the rest of the metadata record carefully for additional details. The landslide probability data has the same resolution as the base used in the overlaying of the raster layers which is the USGS 2009 National Elevation Dataset (NED). It has a cell size of 1/3 arc-second (approximately 10 meters). No formal positional accuracy tests were conducted The GIS map layers (shapefiles and rasters) are geoprocessed in ArcGIS 10.3 using various Spatial Analyst Tools and raster calculations are done within ModelBuilder using a customized Map Algebra expression. 20161001 Raster Grid Cell 22514 19938 NAD 1983 Albers 34.0 40.5 -120.0 0.0 0.0 -4000000.0 coordinate pair 3.754707655900803E-9 3.754707655900803E-9 METERS D North American 1983 GRS 1980 6378137.0 298.257222101 pf The potential of widespread slope failures, in terms of landslide probability, triggered by a M7.0 scenario earthquake on the Hayward Fault.
