Short summary
Short summary
Using novel geophysical datasets, we reassess the slip rate of the Morne Piton fault (Lesser Antilles) at 0.2 mm yr−1 by dividing by four previous estimations and thus increasing the earthquake time recurrence and lowering the associated hazard. We evaluate a plausible magnitude for a potential seismic event of Mw 6.5 ± 0.5. Our multi-segment tsunami model representative of the worst-case scenario gives an overview of tsunami generation if all the fault segments ruptured together.

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.

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.

New satellite geodetic data (PS-InSAR) evidence a generalized subsidence and an eastward tilting of southeastern Sicily combined with a local relative uplift along its eastern coast. We perform flexural and elastic modeling and show that the slab pull force induced by the Ionian slab roll-back and extrado deformation reproduce the measured surface deformation. Finally, we propose an original seismic cycle model that is mainly driven by the southward migration of the Ionian slab roll-back.

This research shows how lake sediments reveal seismic activity history over extended periods, surpassing historical records. Sediment analysis from Lake Aiguebelette in the Western Alps found 32 layers likely caused by earthquakes over the Holocene. Robust dating methods correlated these layers with known historical earthquakes. Results suggest Lake Aiguebelette's sediment records mainly reflect local seismic events, enhancing understanding of earthquake recurrence and regional seismic history.

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.

Short summary
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.

Short summary
By analyzing historical and instrumental seismic data, fault knowledge, and geodetic measurements, we provide a new understanding of seismic hazard in the Lesser Antilles via seismotectonic zoning. We propose new models that can have a significant impact on seismic hazard assessment, such as the inclusion of mantle wedge seismicity, the inclusion of volcanic seismicity, and a complete revision of the subduction interface zoning.
