| Abstract: | This paper presents an evaluation of the lava flowhazard on Lanzarote (Canary Islands) by means of aprobabilistic maximum slope model. This model assumesthat the topography plays the major role indetermining the path that a lava flow will follow. Thearea selected for containing future emission centreshas been chosen taking into account thecharacteristics of the recent eruptive activity andthe present activity of the island. The results of thesimulations constitute hazard maps whose values ateach point represent the probability of being coveredby lava. These results are qualitatively analysed toprovide some indication of the risk to the lifelines(electricity, drinking water etc.) of the island. |
