Washington Play Fairway Analysis - Analysis of High Precision GPS Time Series and Strain Rates for the Cascade Range

Published by AltaRock Energy Inc | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-05-13T19:55:30Z
Global Positioning System (GPS) time series from the National Science Foundation (NSF) Earthscope's Plate Boundary Observatory (PBO) and Central Washington University's Pacific Northwest Geodetic Array (PANGA). GPS station velocities were used to infer strain rates using the "splines in tension" method. Strain rates were derived separately for subduction zone locking at depth and block rotation near the surface within crustal block boundaries.
