The north Ligurian margin is a complex geological area in many ways. It has witnessed several phases of highly contrasting deformation styles, at both crustal scale and that of shallower cover tectonics, simultaneously or in quick succession, and with significant spatial variability. This complex interplay is mirrored in the resulting intricate...

The Southwestern Alps and the Ligurian margin is a region of moderate seismicity with a high rate of small to moderate events. Identifying the active faults in this very densely populated region is critical to better assess the hazard and mitigate the risk. An accurate 3-D velocity model of the shallow to middle crust is a fundamental step to...

Des millions d'Européens vivent dans les régions alpines et sont affectés par la chaîne de montagne, que ça soit par sa topographie, sa géologie ou les risques naturels qu'elle engendre (séismes, mouvements de terrain). Les géologues ont étudié les Alpes depuis plus de 100 ans, ce qui en fait un laboratoire naturel unique pour produire de la...

We present the framework of the modeling package IonoSeis. This software models Global Navigation Satellite System (GNSS) derived slant total electron content (sTEC) perturbations in the ionosphere due to the interaction of the neutral atmosphere and charged particles in the ionosphere. We use a simplified model to couple the neutral particle...

The French–Italian Riviera faces several geophysical hazards, including recurrent earthquakes and underwater landslides that can be tsunamigenic. The stakes are high since this is a densely populated and touristic area. Several studies have already been carried out, in particular to map tsunami hazard resulting from the near-field seismicity of...

AlpArray est un consortium de projets de recherche d'une dizaine de pays européens qi vise à préciser les structures profondes des Alpes (croûte et manteau supérieur) pour mieux comprendre la dynamique de la chaîne. AlpArray s'est appuyé sur le déploiement d'un réseau sismologique dense et homogène (maille ~50 km) à terre et en mer, sur 11...

The Hellenic subduction system exhibits a fairly atypical structure, resulting from the intense radial extension undergone by the Aegean domain from Eocene to Miocene. It features a very wide fore-arc, that itself includes an external non-volcanic arc between southeastern Peloponnesus and southwestern Anatolia, with Crete occupying a frontal...

In the last decade, seismic imaging below salt/basaltic bodies proved beyond doubt to be the most challenging task using conventional strategies in terms of surveying, processing and inversion. Recent innovations across the whole workflow pushed further the resolution limit in such complex environments for resource exploration purposes. On the...

We focus on the northern Ligurian margin, at the geological junction of the subalpine domain and the Ligurian oceanic basin, in order (1) to identify the location of the southern limit of the Alpine compressive domain during the Cenozoic, and (2) to study the influence of a compressive environment on the tectonic and sedimentary evolution of a...

Le bassin Ligure, à la jonction entre la mer Méditerranée occidentale et la chaîne Alpine, résulte d'une extension arrière-arc liée au retrait de la plaque plongeante Ionienne depuis l'Oligocène jusqu'au Miocène. Cette phase d'extension prenant place dans le contexte de la collision Eurasie-Afrique a créé des structures complexes dans une...

The north Ligurian margin is a stretched continental margin located at the junction of the Western Mediterranean Sea and the Alpine belt. The back-arc Ligurian basin opened from late Oligocene to early Miocene, as a result of the Apulian slab rollback. It has then evolved next to the active Alpine orogen, in a regional compressional setting...

The north Ligurian margin is a stretched continental margin located at the junction of the Western Mediterranean Sea and the Alpine belt. This region underwent several phases of contrasting deformation styles. The Ligurian basin opened from late Oligocene to early Miocene times, as a result of a back-arc extension induced by the rollback of the...

The first leg of the SEFASILS cruise took place in November 2018 onboard the RV Pourquoi-Pas ?Up-to-date multichannel and wide-angle seismic data were acquired offshore Monaco, from margin to basin, aiming at providing a renewed vision of the complex North Ligurian backarc system. The compressive and extensive tectonic phases that have closely...
