Recherche

Ma recherche porte essentiellement sur la géodynamique des zones de subduction en m’appuyant sur les observations issues notamment de campagnes océanographiques, à la fois régionalement comme par exemple à Taiwan ou dans les Antilles mais aussi globalement afin de constituer des bases de données exhaustives permettant de tester certains processus caractéristiques grâce à des modèles numériques ou analogiques.
Mes centres d’intérêts actuels concernent les conditions d’initiation des zones de subduction, l’effet de la rugosité de l’interface de subduction sur son comportement sismogène, l’histoire tectonique du système de subduction des Petites Antilles, la structure profonde et l’aléa sismique à l’est de Taiwan.

Nous avons développé un outil informatique Submap en accès libre facile d’utilisation, très utile lorsqu’on se pose des questions sur les caractéristiques de telle ou telle zone de subduction, mais aussi dans le cadre de l’enseignement pour accompagner les étudiants dans la réalisation d’illustrations de zones de subduction particulières. L’outil permet de réaliser des cartes, coupes et fiches de paramètres de zones de subduction incluant des données géodynamiques telles que bathymétrie, sismologie, gravimétrie ou encore cinématique.

Un second outil en ligne en accès libre, appelé Subquake, permet de télécharger des données sur les séismes de subduction de Mw≥7.5 (épicentres, rupture, aspérités).

English version

My research focuses on the geodynamics of subduction zones using observations from oceanographic campaigns, both regionally, such as in Taiwan or the Lesser Antilles, and globally, in order to build up exhaustive databases that can be used to test characteristic processes using numerical or analogical models.

My current interests concern the initiation conditions of subduction zones, the effect of the roughness of the subduction interface on its seismogenic behavior, the tectonic history of the Lesser Antilles subduction system, the deep structure and the seismic hazard in eastern Taiwan.

We have developed an easy-to-use open-access Submap tool, which is very useful when one has questions about the characteristics of a particular subduction zone, but also in the context of teaching to assist students in making illustrations of particular subduction zones. The tool allows the creation of maps, sections and parameter sheets of subduction zones including geodynamic data such as bathymetry, seismology, gravimetry or kinematics.

A second open-access online tool, called Subquake, allows downloading data on subduction earthquakes of Mw≥7.5 (epicenters, rupture, asperities).
