Resumo:Lava flow emplacement modelling provides about possible future eruptions in a given area and helps, consequently, to better design volcanic hazards zonation maps. The open access plugin Quantum-Lava Hazard Assessment (Q-LavHA), integrated into a Geographic Information System (GIS), includes three different models, two probabilistic and one deterministic, for the simulation of lava flow emplacement and establishes the overlap degree with actual flows. Pico de Bandama volcano lava flow (1970 ± 70 AP) was modelled with Q-LavHA. A high degree of reliability between the model and the reality is obtained, even with the simplest probabilistic models. For a high degree of reliability in modelling ancient eruptions, a detailed palaeogeomorphological reconstruction of the relief prior to the eruption is essential. © 2019 Sociedad Geologica de Espana.
