Tsunamis are among the most deadliest threat of coastal areas and a large number of tropical island are exposed because of their proximity to potential tsunami sources. However, far field sources may represent a threat and thus can not totally be eluded. In the framework of the project C3AF which studies the consequences of climate changes over the French West Indies, we used the numerical model SCHISM (ZHANG et al., 2016) to simulate several potential tsunamis propagation as well as their impacts over the Guadeloupe Island (French West Indies). In this study, we present the simulation of a potential tsunami scenario based on the collapse of the Cumbre Viera volcano, in the Canary Islands (ABADIE et al., 2012) to assess the potential threat of the Guadeloupe archipelago. Several scenario have been simulated and time arrival, wave heights and potential inundation are investigated.
