Additional Information
Title: Estimated maximum-likelihood interseismic extensional strain rate perpendicular to Quaternary faults in Nevada, with fault strike coherence equal to 1. Crustal strain rate based on GPS station measurements.
Description and Methodology: Warmer colors (if the “extmax.avl” file is used for color coding) indicate progressively greater rates of extensional strain perpendicular to the Quaternary fault fabric. Units of strain are mm/yr/1000 km. Calculations are based on maximum likelihood orientation of Quaternary faults (coherence set equal to 1). A regional strain rate field, including all strain matrix components, was calculated from all available GPS stations in the Great Basin (and beyond). That strain rate field was intersected with a map showing the dominant azimuth of Quaternary faults in Nevada, prepared from a Quaternary fault map provided by Craig DePolo of the NBMG (Blewitt, et al., 2002; dePolo and Anderson, 2000).
