Location of Seismic Reflection Line CRmv This dataset provides location information for the seismic reflection line CRmv across Crowleys Ridge in the New Madrid seismic zone, central US. The seismic reflection data are interpreted and discussed in the associated publication Categories: Data; Tags: Arkansas, Central United States, New Madrid, faults, geoscientificInformation, All tags...
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.
