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 a tab-delimited text file. 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.
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...
This dataset contains a provisional release of field observations at sites of fault rupture and ground deformation features where quantitative displacement measurements were obtained. This release does not include associated photographs and some observations where there are outstanding questions about the measurements received; some duplicate observations may exist in this dataset. Photos and resolved measurement data are anticipated for a future release. This dataset consists of a comma-delimited ASCII text file where each line in the file represents an observation, suitable for importing into a spreadsheet, database or GIS application for visualization and analysis. These data are also summarized in a companion...

This release provides the data for a comprehensive survey of geologic structures in the eastern Española Basin of the Rio Grande rift, New Mexico. The release includes data and analyses from 53 individual fault zones and 22 other brittle structures, such as breccia zones, joints, and veins, investigated at a total of just over 100 sites. Structures were examined and compared from poorly lithified Tertiary sediments, as well as Paleozoic sedimentary and Proterozoic crystalline rocks. Data and analyses, include geologic maps; field observations and measurements; orientation, kinematic paleostress analyses and modeling; statistical examination of 575 fault trace lengths derived from aeromagnetic data in the Española...

This data release consists of point data digitized from structural geologic orientation symbols consisting of mostly foliations and lineations. The data comes from primarily Proterozoic aged rocks in the eastern-central Rocky Mountain Front Range of Colorado. Compilation of the data is from twenty-three geologic maps published by the U.S. Geological Survey and the Colorado Geological Survey between 1964 and 2009, primarily using 7.5-minute, 1:24,000 scale quadrangles. Structural geologic orientation data of planar features (e.g., foliations) and linear features (e.g., fold axes), both with associated attribute values of strike and trend, dip and plunge, location, elevation, and geologic unit were captured for more...

This product presents summary information from field observations and photographs (data contained in the associated Observations.txt and Photos.txt data files) in KMZ format, allowing for: a) viewing the data in a spatial context within Google Earth or other earth viewers, b) easily accessing full-resolution photographs; and c) relating this information to mapped fault rupture and ground deformation features. It is intended as a companion dataset to the KMZ representation of fault rupture and ground deformation features located at: https://www.sciencebase.gov/catalog/item/5c1a285ee4b0708288c2b1cf.
This product is the result of a comprehensive compilation of site-specific field descriptions and displacement measurements where tectonic faulting and ground failure produced visible deformation that fractured and disturbed the ground surface. The resultant data is distributed as a tab-delimited text file. All post-earthquake ground rupture observations and slip/displacement measurements are those in the public domain, including data that have been published in summary reports elsewhere.
This item contains a collection of ground photographs taken at the observation stations listed in the above title, showing tectonic faulting and/or ground deformation features produced by the Mw 6.0 South Napa earthquake of August 24, 2014. It is a subset of the a larger collection of photographs found at Photographs of Fault Rupture and Ground Deformation Features Produced by the Mw 6.0 South Napa Earthquake. These photographs may be viewed or downloaded here, but are best viewed in context with fault rupture and other observations from the related KMZ file of summary field observations and photographs obtained during post-earthquake investigations of the Mw 6.0 South Napa Earthquake of August 24, 2014, or from...
This product is a collection of digital data that document fault rupture and ground deformation produced by the August 24, 2014 South Napa Earthquake. These datasets are described and more fully discussed in 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. Included in this collection are: 1) Hillshade images that depict fault rupture, in GeoTIFF format derived from hi-resolution airborne lidar data flown on Sept. 9, 2014; 2) GIS Shapefile and KMZ...
Locations along fault trends and InSAR lineaments where surface faulting was anticipated but where no evidence of ground disturbance was observed. Each record in our Negative Evidence table constitutes a station, which is a location where an observation was made by a single investigator or a field team working together (an observer) during a single visit on particular date.
