| dc.description.abstract | ABSTRACT: A basic model for lava flows simulation is implemented and applied to the Fogo volcano using as a test the April 95 eruption; the objective is to evaluate and control future occurrences. Using the techniques of Cellular Automata (CA) the lava is considered a dynamic system varying in time and space. A Digital Terrain Model (DTM) using discrete cells of 15 metres is created in a Geographic Information System (GIS). A stochastic simulation process is used to establish the lava flow. The set of simulated images over time periods, allows evaluation of the uncertainty of the spatial dispersion of lava, according to its properties, and elaboration of hazard mapping. | pt_PT |
