This product is the result of a comprehensive compilation of site-specific ground photographs taken where tectonic faulting and ground failure produced visible deformation that fractured and disturbed the ground surface. The resultant data is distributed as collection of JPEG image files. All post-earthquake photographs taken by investigators working for public agencies are in the public domain, including data that have been published in summary reports elsewhere. These photographs are best viewed in context with fault rupture and other observations from the related KMZ file of summary field observations and photographs (https://www.sciencebase.gov/catalog/item/5c1d7ae0e4b0708288ca1322), or from the associated open-file report appendixes (Ponti, D.J, Rosa, C.M, and Blair, J.L., 2019, The Mw 6.0 South Napa Earthquake of August 24, 2014—Observations of surface faulting and ground deformation, with recommendations for improving post-earthquake field investigations: U.S. Geological Survey Open-File Report 2019–1018, https://doi.org/10.3133/ofr20191018.). The FGDC metadata file associated with this item provides attribute information for all photographs in all of the child items of this photo collection.
