• Resumen

  • The hydrographic network of volcanoes has an impact as much on the constructive as on the destructive processes. This study is potentially rich in information. Volcanic hydro-geomorphology studies volcanic hydrographical system from a naturalist and multiscale approach.

    On volcanoes, the analysis of processes that are produced in volcanic streams, during eruptions or rest periods, shows that the hydro-volcano-geomorphologic (HVG) hazards are numerous and cannot be reduced to simple flooding. All of the different HVG destructive phenomena act to evacuate the excess of volcanic material. The morphological impact is more definite than the "standard" water floods. As a result, the threat of volcanic streams is significant because it is frequent, spontaneous and cannot always be predicted. Which bring us to the following question: are volcanic streams more dangerous than eruptions? If the HVG risks have been neglected by the society in favor of the crater phenomena, it has not always been so in the Lesser Antilles. The vocabulary of the native Caribbean (Kalinago) that has reached us through the Carib-French dictionary of Father Breton (1665) is rich in information. It allows us to identify several gradients in the hydro-geomorphologic factors: meteorological crisis, stability of land and torrential phenomena intensity. The Kalinago's vocabulary contains other words from different domains in geosciences, but none which refer to volcanic eruptions. This amerindian society probably perceived volcanoes on another time scale than ours: a temporal scale adapted to the impact of hazards, their danger.
