Abstract

We use 2.5 to 14 years long position time series from >800 continuous Global Positioning System (GPS) stations to study vertical deformation rates in the Euro‐Mediterranean region. We estimate and remove common mode errors in position time series using a principal component analysis, obtaining a significant gain in the signal‐to‐noise ratio of the displacements data. Following the results of a maximum likelihood estimation analysis, which gives a mean spectral index ~ −0.7, we adopt a power law + white noise stochastic model in estimating the final vertical rates and find 95% of the velocities within ±2 mm/yr, with uncertainties from filtered time series ~40% smaller than from the unfiltered ones. We highlight the presence of statistically significant velocity gradients where the stations density is higher. We find undulations of the vertical velocity field at different spatial scales both in tectonically active regions, like eastern Alps, Apennines, and eastern Mediterranean, and in regions characterized by a low or negligible tectonic activity, like central Iberia and western Alps. A correlation between smooth vertical velocities and topographic features is apparent in many sectors of the study area. Glacial isostatic adjustment and weathering processes do not completely explain the measured rates, and a combination of active tectonics and deep‐seated geodynamic processes must be invoked. Excluding areas where localized processes are likely, or where subduction processes may be active, mantle dynamics is the most likely process, but regional mantle modeling is required for a better understanding.

  • The inferred maximum post-LIA uplift rate of up to a few mm yr-1 from experiments with or without a low asthenospheric thermal anomaly (TA ≤ 100 °C) is within the same order of magnitude of maximum uplift rates measured in collisional orogens such as the European Alps and the Himalayas.

    “The inferred maximum post-LIA uplift rate of up to a few mm yr -1 from experiments with or without a low asthenospheric thermal anomaly (TA ≤ 100 °C, Fig. 7c) is within the same order of magnitude of maximum uplift rates measured in collisional orogens such as the European Alps”

    From Fast uplift in the southern Patagonian Andes due to long- and short-term deglaciation and the asthenospheric window underneath (2024) · cites this paper as Serpelloni et al., 2013

    Section 6.2 (p. 15) reports measured Alpine uplift of about 1–2 mm/yr, with central Alpine rates exceeding 2 mm/yr. That supports the same-order-of-magnitude comparison for the European Alps. The supplied claim also names the Himalayas, but the cited paper’s passages do not establish Himalayan uplift rates; the post-LIA experiments are the citing authors’ own context. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
