Fig. 2: Postseismic surface displacements from geodetic data and model results.
From: Pore-pressure diffusion controls upper-plate aftershocks of the 2014 Iquique earthquake
Comparison between the observed and predicted postseismic surface displacement during the first 270 days after the mainshock. a Cumulative displacements from the modeled afterslip, poroelastic, and non-linear viscoelastic relaxation compared to Global Navigation Satellite System (GNSS) observations. Color-coded inverted afterslip on the plate interface is exhibited in the background. b–g Comparison of the horizontal and vertical postseismic displacement time-series between modeled (black lines) and GNSS daily solutions (olive dots) from the three GNSS stations PSGA, IQQE, and COLC. The total modeled deformation (black) is also decomposed into the relative contribution of afterslip (red dashed lines), poroelasticity (blue lines), and non-linear viscoelastic relaxation (grey dashed lines).
