GNSS Observations of the Land Uplift in South Africa: Implications for Water Mass Loss

Journal of Geophysical Research Solid Earth, Год журнала: 2025, Номер 130(4)

Опубликована: Апрель 1, 2025

Abstract Continuously operating Global Navigation Satellite System (GNSS) base stations in South Africa show a spatially coherent vertical displacement. While one hypothesis attributes this motion to crustal deformation from mantle flow and dynamic topography (Hammond et al., 2021, https://doi.org/10.1029/2021jb022355 ), we propose an alternative explanation. Our evidence suggests that land water loss multiple droughts is major driver of the observed uplift. In study, analyze daily Positioning (GPS) height time series 2000 2021. We use singular spectral analysis (SSA) separate long‐term trends annual semi‐annual signals noise. The processed were inverted into mass loading on uniform grid, with Earth's crust's rheological properties defined by Preliminary Reference Earth Model (PREM). experimental approach 2 grid resolution provides suitable results for most Africa. GPS‐derived total storage change reconcile well GRACE‐assimilated solution hydrological model at monthly scale across different provinces, showing correlations up 90% 94%, respectively. trend averaged over country shows considerable correlation 46% 53%, These provide strong uplift primarily origin.

Present‐Day Three‐Dimensional Crustal Deformation Velocity of the Tibetan Plateau Due to Multi‐Component Land Water Loading

Abstract Quantitative understanding of the land water loading is a prerequisite to construction reliable tectonic deformation velocity field in Tibetan Plateau (TP). Here, for first time, we image three‐dimensional crustal each component TP. Our results reveal that signal strength six components ranks from largest smallest as groundwater, glacier, lake, soil water, permafrost, and snow, with maximum vertical close ±1.60 mm/yr horizontal exceeding 0.40 mm/yr. All can achieve strong enough present‐day Global Positioning System (GPS) at some sites. But loading, apparent impacts are only lake however, very limited, absolute ratio GPS being smaller than 5% almost all
