Geoformas volcánicas insulares para el reconocimiento de la capacidad eruptiva y alcance de la exposición de la población y daños a la flora

Abstract

Abstract:The generation of both real and hypothetical eruptive scenarios allows us to estimate the areas exposed to an eruption in order to delimit imminent danger zones in the ocurrenceof an eruptive event, whose parameters are difficult to estimate and depend on factors that cannot be controlled.The study was carried out on Isabela Island in the Galapagos archipelago based on the generation of lava flows through geological structures on four of its six volcanoes.The model obtained shows the area of endemic flora and animal species that could be affected after a hypothetical or real eruptive event; it also provides the zones that comprisea danger to the inhabitants of the rural area. In the southeastern zone of the Sierra Negra volcano, according to the recreated scenarios, the risk to both residents and tourists must be evaluated.
