Short summary
Short summary
The south-east of France is the most seismically active region in metropolitan France; however, seismicity remains low to moderate and surface deformation rates low. Alongside a complex geological structure, this region is a challenge for seismic hazard assessment. We propose seismic source characterization through zone models by assessing seismotectonic behavior from three different perspectives: crustal structure, observed seismicity and surface deformation.

Sub-annual glacier surface velocity derived from remote sensing images are receiving increasing attention. In the meantime, systematic seasonal errors (i.e. biases) have been reported in time series derived from optical images on various landforms, such as landslides or dunes. The extent to which such biases affect glacier velocity maps remains poorly investigated. Here, we propose characterizing the amplitude and spatial distribution of these seasonal biases.

Short summary
Short summary
Changes in water reaching the base of glaciers strongly affect their sliding speed by altering water pressure beneath the ice. High water pressure is often thought to develop during summer melt, enlarging cavities at the glacier base and increasing sliding speed. Our observations show instead that the cavities mainly grow during winter, when water pressure builds up in isolated cavities. As the cavities become connected during the melt season, water pressure decreases and the glacier slows down.

We present a fault-related data compilation, named South-East France Potentially Active Faults (SEFPAF). It integrates structural components and presents a fault classification by importance, amount of documentation and seismogenic potential. This last parameter is assessed by analysing the amount of observed seismicity near the faults, amount of surface deformation estimated from GNSS velocities, and the age of the last known rupture on the fault.

Marine terrace sequences – staircase-shaped coastal landforms – record sea-level changes, vertical motions, and erosional processes that are difficult to untangle. To achieve this, we developed a numerical inversion approach: using the observed landscape as input, we constrained the ensemble of parameter ranges that could have created this landscape. We applied the model to marine terrace sequences in Santa Cruz (US) and Corinth (Greece) to reveal past sea or lake levels, uplift rates, and hydroclimates.

Short summary
The flow of glaciers and ice sheets results from ice deformation and basal sliding driven by gravitational forces. Quantifying the rate at which ice deforms under its own weight is critical for assessing glacier evolution. This study uses borehole instrumentation in an Alpine glacier to quantify ice deformation and constrain ice viscosity in a natural setting. Our results show that the viscosity of ice at 0 °C is largely influenced by interstitial liquid water, which enhances ice deformation.

This study presents the European Fault-Source Model 2020 (EFSM20), a dataset of 1248 geologic crustal faults and four subduction systems, each having the necessary parameters to forecast long-term earthquake occurrences in the European continent. This dataset constituted one of the main inputs for the recently released European Seismic Hazard Model 2020, a key instrument to mitigate seismic risk in Europe. EFSM20 adopts recognized open-standard formats, and it is openly accessible and reusable.

Uplift rates up to 40 mm yr−1 are measured by GNSS in the southern Patagonian Icefield, a remainder of the Patagonian Ice Sheet that covered the Andes in the Last Glacial Maximum (LGM) at 26 ka. Using numerical modelling, we estimate an increase of 150 to 200 °C of the asthenospheric temperature due to the slab window under southern Patagonia, and we show that post-glacial rebound, after the long-term LGM and the short-term Little Ice Age (400 a), contributed to the modern uplift rate budget.

We study the construction of the Ukrainian Carpathians with LT thermochronology (AFT, AHe, and ZHe) and stratigraphic analysis. QTQt thermal models are combined with burial diagrams to retrieve the timing and magnitude of sedimentary burial, tectonic burial, and subsequent exhumation of the wedge's nappes from 34 to ∼12 Ma. Out-of-sequence thrusting and sediment recycling during wedge building are also identified. This elucidates the evolution of a typical wedge in a roll-back subduction zone.

Short summary
This work features the highest-resolution seismic stress and strain fields available at the present time for the analysis of the active crustal deformation of the Western Alps. In this paper, we address a large dataset of newly computed focal mechanisms from a statistical standpoint, which allows us to suggest a joint control from far-field forces and from buoyancy forces on the present-day deformation of the Western Alps.
