Datasets documenting late Pleistocene faulting in the Pondosa fault zone, Pit River Region, Northeastern California
공공데이터포털
These datasets provide bedrock mapping and geochemistry, low-temperature thermochronology, remotely mapped lineaments, field observations of interpreted faults, and structure from motion models in the Pit River Region of northeastern California. The bedrock mapping datasets contain bedding orientations and field rock descriptions and associated geochemistry and 40Ar/39Ar data for a limited number of samples. Low-temperature thermochronology datasets contain (U-Th)/He measurements for two samples from the Klamath terranes. Remotely mapped lineaments, field observations of lineaments, and structure from motion models document the Quaternary-active faults in the region. Simplified fault traces for interpreted Quaternary-active faults are provided for seismic hazard studies. These datasets are associated with the manuscript: Thompson Jobe, J.A., R. Briggs, R. Gold, S. DeLong, M. Hille, J. Delano, S. A. Johnstone, A. Pickering, R. Phillips, A. T. Calvert (in review).

Faults--Monterey Canyon and Vicinity Map Area, California
공공데이터포털
This part of DS 781 presents fault data for the geologic and geomorphic map of the Monterey Canyon and Vicinity map area, California. The vector data file is included in "Faults_MontereyCanyon.zip," which is accessible from http://pubs.usgs.gov/ds/781/MontereyCanyon/data_catalog_MontereyCanyon.html. These data accompany the pamphlet and map sheets of Dartnell, P., Maier, K.L., Erdey, M.D., Dieter, B.E., Golden, N.E., Johnson, S.Y., Hartwell, S.R., Cochrane, G.R., Ritchie, A.C., Finlayson, D.P., Kvitek, R.G., Sliter, R.W., Greene, H.G., Davenport, C.W., Endris, C.A., and Krigsman, L.M. (P. Dartnell and S.A. Cochran, eds.), 2016, California State Waters Map Series—Monterey Canyon and Vicinity, California: U.S. Geological Survey Open-File Report 2016–1072, 48 p., 10 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20161072. Faults in the Monterey Canyon and Vicinity map area are identified on seismic-reflection data based on abrupt truncation or warping of reflections and (or) juxtaposition of reflection panels with different seismic parameters such as reflection presence, amplitude, frequency, geometry, continuity, and vertical sequence. Faults were primarily mapped by interpretation of seismic reflection profile data from USGS field activities S–N1–09–MB and S–6–11–MB. The seismic reflection profiles were collected in 2009 and 2011.
Digital database for the geologic map along the southern Bartlett Springs fault zone and adjacent area between Cache Creek and Lake Berryessa, Northern Coast Ranges, California
공공데이터포털
This geologic map database is comprised of new geologic mapping, at a 1:24,000 scale, along the southern Bartlett Springs fault in the northern California Coast Ranges. The map covers an area of 258 square miles in Lake, Napa, Colusa, and Yolo counties, work was undertaken between 2016 and 2021, and supported by the USGS National Cooperative Geologic Map Program. This geodatabase contains the most up-to-date and highest resolution mapping in the region. Results and observations reported here help elucidate the geologic deformational history, as well as relationships between active older and active structures. Please consult the map pamphlet and description of map units for a detailed presentation and interpretation of data and discussion of results. The report and geodatabase contain two plates including the geologic map as well as a correlation of map units, four geologic cross sections, six microseismic cross sections, and a microseismicity fault map.

Faults in the Hueneme Canyon and Vicinity map area are identified on seismic-reflection data based on abrupt truncation or warping of reflections and (or) juxtaposition of reflection panels with different seismic parameters such as reflection presence, amplitude, frequency, geometry, continuity, and vertical sequence. Faults were primarily mapped by interpretation of seismic reflection profile data from USGS field activities Z–3–07–SC and S-7-08-SC. The seismic reflection profiles were collected in 2007 and 2008.
Pre-existing features associated with active faulting in the vicinity of the 2019 Ridgecrest, California earthquake sequence
공공데이터포털
This dataset is composed of linear active tectonic and other relevant features (scarps, deflected drainages, and lineaments and contrasts in topography, vegetation, and ground color) mapped based on high-resolution topography, aerial/satellite imagery, and field observations. The mapping covers the area surrounding the 2019 Ridgecrest, California earthquake surface ruptures. Point locations of field observations are also included.
