Abstract - Earthquakes, Tsunamis and their cross-calibration : The 26th December 2004 case study We present here features linking earthquakes and tsunamis. For a tsunamigenic earthquake, their respective informations may help as a cross-calibrating, and thus, both co-seismic displacement and tsunami propagation can be better characterized. In...

As with earthquakes, river floods, water waves, and wind intensities, a tsunami intensity has to be synthetic and comprehensive to be efficient. Tsunami impact is complex because the effects can be felt on the beach, on inundated areas and also at berths and anchors. Within the same local area, a tsunami may severely impact the population on...

Numerical calculations of the resonant interactions of three-dimensional short-crested waves very near their two-dimensional standing wave limit are performed for water of uniform depth. A detailed study of the properties of the solutions indicates that both classes of waves admit multiple solutions that are connected to each other through...

À la fin du XIXe siècle, un tremblement de terre ravageait la Riviera franco italienne. Une nouvelle étude montre qu'il a été bien plus fort qu'on ne le croyait. Cette découverte amène les géologues à réévaluer le risque sismique de la région.

The tsunami hazard in Martinique due to local, regional and distant seismicity is investigated. Former deterministic scenarios are processed. They were proposed elsewhere based on historical records and the analysis of the morpho-tectonics of the area, i.e., two local subduction scenarios of magnitudes Mw 7.5 and Mw 8.0 representative of the...

The Ligurian coast, located at the French–Italian border, is densely populated as well as a touristic area. It is also a location where earthquakes and underwater landslides are recurrent. The nature of the local tsunamigenesis is therefore a legitimate question, because no tsunami warning system can resolve tsunami arrival times of a few...

Short-crested waves are three-dimensional waves that may be generated through a reflection of a two-dimensional Stokes wave on a seawall. Thus, they are more likely to be observed near ports or any consequent marine structure. Two numerical methods are used to compute three-dimensional surface gravity short-crested waves on deepwater. The first...

ABSTRACT In this article, we estimate the tsunami hazard in Martinique due to tsunamis generated by earthquakes associated with the Lesser Antilles subduction zone. Using a deterministic approach based on reliable earthquake scenarios, we use high-resolution bathymetric and topographic data to model tsunami propagation and inundation with...

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...
