  abstract = {{T}o investigate the spatiotemporal evolution of salars in the {A}tacama {D}esert in {C}hile (24-26 degrees {S}), we use a deformation time series retrieved by applying satellite radar interferometry techniques for the period from 2003 to 2008. {W}e find that all 12 salars surveyed are actively deforming, with displacement rates from -1.4 to 1.5 cm/yr in the satellite line-of-sight direction. {D}isplacement rates are mostly confined to the salars themselves, and are generally constant in time and space. {T}o understand the reason for this displacement signal, we further compare these observations with {LANDSAT} imagery and field observations. {R}elationships between these observations suggest that the most rapid uplift regions indicate subsurface material accretion. {A} variety of saline sedimentary processes related to the salar hydrology can explain this accretion, the most likely being capillary halite precipitation within and below surficial salt crusts. {W}e further propose that salars, whose dynamics are dependent on the presence of brine and resurging saline groundwater, may be used as potential indicators of water resource evolution in the central {A}ndes, and in similar water-limited regions elsewhere on earth.},
