Modelización morfológica y morfométrica de erupciones volcánicas recientes generando plataformas costeras: caso estudio del volcán de Montaña del Tesoro (El Hierro, Islas Canarias)

Abstract

This paper deal about GIS methods applied to volcanism affecting coastal platforms. The developed methodology is based on an intensive and accurate geological field work allowing quantitative comparision of the present day littoral geomorphology with those ones of the pre- and post-eruptive times. The Montaña del Tesoro Holocene volcanic eruption (El Hierro island, Canaries) was selected as case study to develop and calibrate the modelling due to the excellent exposition of the volcanic formations and also the detailed topographic and bathymetric maps available of this area. Resulting models give quantitative information on the aggradation associated with the eruption, as well as on the degradation related to both the littoral and fluvial erosions.
