Tectonic versus glacial isostatic adjustment deformation in Europe

, 2002
Tectonic deformation induced by the Alpine collision and Glacial Isostatic Adjustment (GIA) in Europe are modelled by means of a finite element scheme and viscoelastic normal modes techniques in order to compare the resulting deformation patterns with ...

Characterization of the Plumbing System Beneath Askja Caldera, Iceland, Revealed by Microgravity and Deformation Data During Uplift Between 2022 and 2023

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract In July 2021, an episode of uplift started at Askja caldera, Iceland, following over 50 years of subsidence. The initial inflation rate was approximately 700mm/yr $700\hspace*{.5em}\mathrm{m}\mathrm{m}/\mathrm{y}\mathrm{r}$, declining to 350mm/yr $350\hspace*{.5em}\mathrm{m}\mathrm{m}/\mathrm{y}\mathrm{r}$ within 1 month.

GNET Derived Mass Balance and Glacial Isostatic Adjustment Constraints for Greenland

Geophysical Research Letters
Monitoring the Greenland mass balance (GMB) is crucial in the context of global sea level rise. Currently, three main methods are used to measure GMB, with the primary source of uncertainty arising from the glacial isostatic adjustment (GIA) contribution.

Glacial-Isostatic Adjustment-II. The Inverse Problem [PDF]

Geophysical Journal of the Royal Astronomical Society, 2007
Summary The principle of correspondence is invoked to determine Laplace transform domain solutions to the surface mass loading problem for radially stratified visco-elastic (Maxwell) spheroids. These Laplace transform domain solutions are expressed in terms of visco-elastic analogues of the conventional surface load Love numbers of elasticity. These

GIA‐Induced Mantle Circulation and Surface Horizontal Motions in North America: Effects of 3D Laterally Varying Elastic Thickness and Viscosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The horizontal surface motions of the Earth's crust induced by glacial isostatic adjustment (GIA) are highly sensitive to lateral variations in Earth properties. We construct 3D GIA models by incorporating both varying elastic lithospheric thickness and lateral viscosity variations in the asthenosphere in a global, compressible, self ...

Reconstruction of Holocene sea-levels using diatom- and pollen-based microfossil transfer functions, west coast of Scotland, UK [PDF]

, 2007
Due to its sensitivity to isostatic and eustatic sea-level change the west coast of Scotland has been an important area for studying sea-level change. Recently, data from north west Scotland have been used to refine GIA models because of the presence of ...

Present-day gravity changes induced by glacial isostatic adjustment from ensemble simulations with 3D Earth structures

, 2023
We provide present-day glacial isostatic adjustment (GIA) gravity changes simulated with the numerical model VILMA. The effects of Earth and ocean pole tide due to rotational deformation (considered in VILMA) were removed.

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]

, 2014
This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...

On the Accuracy of Glacial Isostatic Adjustment Models for Geodetic Observations to Estimate Arctic Ocean Sea-Level Change

Terrestrial, Atmospheric and Oceanic Sciences, 2013
Arctic Ocean sea-level change is an important indicator of climate change. Contemporary geodetic observations, including data from tide gages, satellite altimetry and Gravity Recovery and Climate Experiment (GRACE), are sensitive to the effect of the ...
