Dynamics of plate boundary fault systems from Basin and Range Geodetic Network (BARGEN) and geologic data. Brian Wernicke et al.
This paper presents results of 2-3 years of continuous monitoring of a new 50-station network of GPS (global positioning system) stations that were installed across the northern Basin and Range Province of the western United States. This project, funded by the NSF Continental Dynamics Program, represents a significant technological advance by documenting that continuous recording of carefully installed GPS stations can provide precise measurements (with errors possibly significantly lower than 0.5 mm per year) of tectonic displacements of station sites in the Basin and Range Province relative to the stable interior of North America. The results provide a view of the velocity field of stations that can be used to understand the extensional deformation (strain) of the Basin and Range Province. Results are also evaluated to answer important questions for continental tectonics: Is the
