GPS displacement observations and gravity-derived displacement predictions. Vertical-component GPS displacements for 10 sites with the longest observation periods around the NMSZ (blue points). For processing details, see Methods. Site locations are given in Supplementary Table 1. Time series are corrected for instrumentation-related offsets. Grey bars are 1σ uncertainties. GPS site locations, identified by the site ID shown in the lower left of each panel are shown in Fig. 1a. Red points are vertical-component displacements calculated for a layered-elastic spherical Earth response to GRACE-observed surface load variations (see Methods). A best-fit linear trend has been removed from both GPS and gravity-derived time series. Blue and red lines show a best-fit 24-component Fourier series to the GPS and gravity time series, respectively
