In the Mediterranean Sea, the probability that a large earthquake-triggered tsunami will occur in the coming decades is high. Historical tsunami database informs us on their geographical occurrence but their sources, i.e., the faults that slipped during earthquakes and displaced the seafloor to generate tsunamis, are often unknown. Here we identify...
The seismic hazard posed by submarine faults and the capacity of submarine earthquakes to trigger mass wasting are poorly understood because we lack detailed characterizations of coseismic ruptures at the seafloor. Here, we present comprehensive mapping of a seafloor rupture caused by the 2004 Mw 6.3 Les Saintes earthquake on the Roseau normal faul...

The Alboran Sea (Western Mediterranean) is a relatively s...
We develop and propose a solution allowing the visualization and interpretation within a VR environment of Digital Elevation Models and 3D models derived from Structure From Motion, so as to conduct quantitative geomorphological/geological analyses. For this, we use an Oculus Rift headset, Touch controllers and the Unity game engine. We have develo...
Based on swath bathymetry, two-dimensional, high-resolution
seismic reflection profiles, and Ocean Drilling Program/Deep Sea
Drilling Project (ODP/DSDP) data, we describe a seafloor honeycomb
pattern and propose a model for its formation in Pliocene–Miocene
carbonate deposited on the uneven oceanic basement of the Carnegie
Ridge (offshore Ecuador)....
With hull-mounted multibeam echosounder data, we report for the first time along the active Ecuadorian margin, acoustic signatures of water column fluid emissions and seep-related structures on the seafloor. In total 17 flare-shaped acoustic anomalies were detected from the upper slope (1250 m) to the shelf break (140 m). Nearly half of the flare-s...
Time-series bathymetric data acquired from 1967 to 2011 are used to evaluate the morphological evolution of the continental shelf and upper continental slope off the city of Nice (SE France, Ligurian Sea). Mapping in water depths of 0–300 m was undertaken to identify the changing morphology of landslide scars and their erosive chutes. Quantitative...

Time-series bathymetric data acquired between 1991 and 2011 have been used to evaluate the recent morphological evolution of the Nice upper continental slope (SE France, Ligurian Sea). Small-scale landslides lead to a retrogressive evolution of the continental shelf/upper slope transition but their frequency, size and impact are not well known. Map...
preliminary results on size and impact of small-size landslides presented to ISSMMTC
