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...

This database contains geometries and basic parameters for fault sections conisdered in earthquake rupture forecasts and probabilistic seismic hazard models (specifically, NSHM23).

This dataset contains simplified fault traces, derived from the lineament mapping, for the Pit River region, northeastern California.

This database consists of geologic slip rate information and metadata used to constrain NSHM23 geodetic and geologic deformation models.

This dataset contains linework for a simplified Quaternary fault map of Puerto Rico, and is described in Table 4 and Figure 24 in the related manuscript. Faults are classified into three different classes based on the presence or absence of geologic evidence for Quaternary fault activity and tectonic origin, and this dataset includes faults that may have weak, equivocal, or limited evidence for Quaternary deformation or tectonic origin. See related manuscript for additional details on interpretation and use of the linework. Related manuscript: Thompson Jobe, J. A. R. Briggs, K. S. Hughes, J. Joyce, R. Gold, S. Mahan, H. Gray, L. Strickland (in review). Neotectonic mapping of Puerto Rico.

This dataset provides line work of fault, fold, and unknown scarps mapped along the margins of Crowleys Ridge in the New Madrid seismic zone, Arkansas and Missouri.

The U.S. National Seismic Hazard Model (NSHM) relies on deformation models to assign slip rates along active faults used in the earthquake rupture forecast. Here, we present the geologic deformation model results in tabular form. We provide model outputs in multiple file formats, as well as the polygons used in analyses throughout the geologic deformation model process.The data presented herein are in support of the following interprative manuscript: Hatem, A.E., Reitman, N.G., Briggs, R.W., Gold, R.D., Thompson Jobe, J.A., Burgette, R.J., (2022) ­­­Western U.S. geologic deformation model for use in the U.S. National Seismic Hazard Model 2023, Seismological Research Letters.
This release provides the data and interpretations supporting evidence of late Quaternary faulting along Crowleys Ridge in the New Madrid seismic zone. The release includes location information for seismic reflection and airborne electromagnetic (AEM) data over Crowleys Ridge, a table of topographic metrics derived from analysis of the 10m National Elevation Dataset (NED) digital elevation model (DEM), a shapefile of scarps mapped on a 1m bare-earth lidar DEM, and a shapefile of a revised New Madrid seismic zone fault network interpretation. These datasets are associated with the publication: Thompson Jobe, J.A., Gold, R.D., Briggs, R.W., Williams, R.A., Stephenson, W.J., Delano, J.E., Shah, A.K., Minsley, B.J.,...

This dataset contains linework of neotectonic mapping from high-resolution lidar-derived topography and historical aerial images on Puerto Rico.
thumbnail
This dataset contains linework of lineaments mapped on 4 <1-m-resolution lidar datasets and the 10-m-resolution National Elevation Dataset digital elevation models in the Pit River region of northeastern California. Lineaments are classified by confidence in tectonic origin, map certainty, and the ages of the bedrock and surficial deposits they cross.
thumbnail
This dataset contains linework of lineaments mapped from 1-m lidar data in the Eastern Tennessee Seismic Zone, Tennessee, USA. Attributes include lineament type, confidence of tectonic origin, and notes on the mapped lineament.
