Gravitational instabilities can be significant threats to populations and infrastructure. For hazard assessment, it is important to estimate the geometry and volume of potential unstable masses. This characterization can be particularly difficult in

International audience; This work focuses on the use of thin-layer models for simulating fast gravitational flows for hazard assessment. Such simulations are sometimes difficult to carry out because of the uncertainty on initial conditions and on sim

The Prêcheur river is located to the West of Montagne Pelée, in the Northern part of Martinique island. For several decades it has produced numerous lahars that directly threaten the Prêcheur village, at the mouth of the river. In recent years,
