Horizontal GPS Velocities


Western US - (Zeng and Shen [2016b]; Herring et al., 2016; McCaffrey et al., [2013])

Southern San Andreas Compilation - (Crowell et al., [2013])




Figure GPS velocity vectors and uncertainties (red) in the area of the CGM [Zeng and Shen, 2016; Herring et al., 2016; McCaffrey et al., 2013; Crowell et al., 2013]. The 1339 vectors are references to the Stable North America Reference Frame (SNARF).  The blue vectors are from a model (0.01˚ grid spacing) using a vector gridding method called gpsgridder [Sandwell and Wessel, 2016].
