Laboratory testing of eight core samples from the Zama field in northwestern Alberta were carried out at the Rock Mechanics Laboratory of the University of Saskatchewan, Saskatoon. Specimens were provided by Advanced Geotechnology. Tests conducted included bulk density, acoustic velocity, uniaxial strength, triaxial strength and, in four cases, residual friction measurements.
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.
