Summary of proposed changes to geologic inputs for the U.S. National Seismic Hazard Model (NSHM) 2023, version 1.0 This data release documents proposed updates to geologic inputs (faults) for the upcoming 2023 National Seismic Hazard Model (NSHM). This version (1.0) conveys differences between 2014 NSHM fault sources and those recently released in the earthquake geology inputs for the U.S. National Seismic Hazard Model (NSHM) 2023, version 1.0 data release by Hatem et al. (2021). A notable difference between the 2014 and 2023 datasets is that slip rates are provided at points for 2023 instead of generalized along the entire fault section length as in 2014; consequently, slip rates are not provided for fault sections in the draft 2023 dataset. Geospatial data (shapefile, kml and geojson) are provided in this data release with...

2D surface strain calculated after removal of UTM reference frame (alternative) Summary: This directory contains a second version of the mosaics of the 2-dimensional (2D) surface strain fields of the 2019 Mw7.1 and Mw6.4 Ridgecrest earthquakes derived from optical correlation. These results are derived through a modification to the inversion approach described in Barnhart et al. 2020 (Nature Geoscience) wherein we remove the UTM reference frame when building the Green’s function that is incorporated into the inversion for the displacement gradient tensor. The removal of the reference frame has the effect of improving the condition number of the Green’s function and making the inversion more stable. The mosaics are in UTM Zone 11N coordinates with 10m spatial resolution. Each file is in units...

Crustal architecture of the transtensional Warm Springs Valley fault zone, northern Walker Lane This data release contains field data for two P-wave seismic reflection profiles acquired across the Warm Springs Valley fault zone, part of the Northern Walker Lane, NV. The dataset consists of high-resolution seismic reflection field records in .segy format, shot coordinates in .csv format, and observers’ logs in .pdf format. The high-resolution seismic profiles are approximately 4 km long. The northern profile (Warm Springs Line 1) is oblique to a prominent fault bounded ridge. The southern profile (Warm Springs Line 2) crosses the northern end of Warm Springs Valley and is nearly co-located with COCORP profile NV-08. To obtain the seismic profiles, we used a 230 kg accelerated weight drop source and a nominal...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
