Note Imagery and 3D textured model of a submarine fault scarp off Les Saintes (French Antilles), at ~1100 m waterdepth, and showing the coseismic trace of the 2004 Les Saintes earthquake. Image processing for the 3D model was carried out with the Matisse software (ref Github). Dataset released as part of a publication by Arnaubec et al (submitted to Computers and Geosciences).

Abstract

Fault scarp along the Roseau normal fault between Les Saintes and Dominica (French Antilles), at a water depth of 1100 m. This fault scarp is sub-vertical and at its base displays a marker that corresponds to the exposed fault plane during the 2004 Les Saintes Earthquake. The model shows here a coseismic displacement of ~1 m. This scarp was one of several surveyed along the Roseau Fault rupture during the Subsaintes cruise (https://doi.org/10.17600/17001000), with ROV Victor 6000 equipped with an HD Video camera. Two datasets are provided. First, the survey imagery, with a video (mp4 format) and an associated navigation file in txt format. Second, a 3D textured model of the site (obj format), together with the a kml file for georeferencing, and a geotiff orthomosaic. This dataset is one of several sets released with a paper by Arnaubec et al. (submitted March 2021, Computer and Geosciences) presenting the Matisse image processing software, and the 3DMetrics Visualization and analysis software (ref Github to come).
