Short summary
The Armorican region (NW France) is marked by several old coastal and marine markers that are today located several tens of meters above sea level. This fact is commonly explained by sea-level variations and complex tectonic processes (e.g., mantle dynamics). In this study, we test the role of the erosion and the associated flexural (lithospheric bending) response. We show that this simple model of flexural adjustment is to be taken into account to explain the regional evolution.

While early scientists believed forests attract rain, later research provided conflicting views, and modern climate models remain inconclusive on natural forests' role in regional pluviometry. Using a parsimony model, we show that continental forests strongly enhance pluviometry if they are connected to underground aquifers. We conclude that natural afforestation should be an efficient way to reactivate precipitation and aquifers recharge.

Since the Pyrenean Last Glacial Maximum (75 ka), the deglaciation of the Ésera glacier (central Pyrenees) was characterized by complex dynamics, with advances and rapid retreats. Cosmogenic dates of moraines along the headwaters of the valley and lacustrine sediments analyses allowed to reconstruct evolutionary history of the Ésera glacier and the associated environmental implications during the last deglaciation and calculate the Equilibrium Line Altitude to determine changes in temperature.

Antarctic permafrost processes are not widely studied or understood in the McMurdo Dry Valleys. Our data show that near-surface permafrost sediments were deposited ~180 000 years ago in Pearse Valley, while in lower Wright Valley sediments are either vertically mixed after deposition or were deposited < 25 000 years ago. Our data also record Taylor Glacier retreat from Pearse Valley ~65 000–74 000 years ago and support antiphase dynamics between alpine glaciers and sea ice in the Ross Sea.

In glaciated regions, induced lithosphere deformation is proposed as a key process contributing to fault activity and seismicity. We study the impact of this effect on fault activity in the Western Alps. We show that the response to the last glaciation explains a major part of the geodetic strain rates but does not drive or promote the observed seismicity. Thus, seismic hazard studies in the Western Alps require detailed modeling of the glacial isostatic adjustment (GIA) transient impact.

Glacial Isostatic Adjustment is considered as a major process of seismicity in intraplate regions such as Scandinavia and eastern North America. We show that GIA associated with the alpine icecap induces a present-day response in vertical motion and horizontal deformation seen in GNSS strain rate field. We show that GIA induced stress is opposite to strain rate, with the paradoxical consequence that postglacial rebound in the Western Alps can explain the strain rate field but not the seismicity.

We develop a two-step methodology combining multiple surface deformation measurements above a salt extraction site (Vauvert, France) in order to overcome the difference in resolution and accuracy. Using this 3-D velocity field, we develop a model to determine the kinematics of the salt layer. The model shows a collapse of the salt layer beneath the exploitation. It also identifies a salt flow from the deepest and most external part of the salt layer towards the center of the exploitation.

Orakei Basin – a former maar lake in Auckland, New Zealand – provides an outstanding sediment record over the last ca. 130 000 years, but an age model is required to allow the reconstruction of climate change and volcanic eruptions contained in the sequence. To construct a relationship between depth in the sediment core and age of deposition, we combined tephrochronology, radiocarbon dating, luminescence dating, and the relative intensity of the paleomagnetic field in a Bayesian age–depth model.

The chronology of historical earthquakes (from historical documents and geological evidence) is still poorly constrained in the western Himalaya. We carried out a field investigation in SW Bhutan along the India–Bhutan border. Our analysis reveals that Bhutan has experienced at least five great earthquakes during the last 2600 years. Coseismic slip values along the Main Himalayan Thrust for most events reach at least 13 m and suggest that associated magnitudes are in the range of Mw 8.5–9.

Short summary
In the Grands Causses area (Southern France), we study the relationship between the evolution of the river, its incision through time, and the location of the nearby caves. It is commonly accepted that horizontal caves are formed during a period of river stability (no incision) at the elevation of the river. Our original results show that it is wrong in our case study. Therefore, another model of cave formation is proposed that does not rely on direct river control over cave locations.
