Abstract

Q-LavHA (Mossoux et al. 2016) is a plugin which simulates lava flow propagation from one or multiple regularly distributed eruptive vents on a Digital Elevation Model (DEM). It combines existing probabilistic and 1D thermo-rheological deterministic (FLOWGO) models and proposes improvements in order to refine the probability of lava flow spatial spread and terminal length. The spatial spread is constrained by the steepest slope following the probabilistic approach of Felpeto et al. (2001). The corrective height factor which is included allows the lava flow simulation to overcome small topographical obstacles and to fill pits. The terminal length of the lava flow simulation can be determined based on a fixed length value, a Gaussian probability density function, or it can be calculated based on the thermo-rheological properties of a cooling open-channel lava flow following the approach of the FLOWGO model (Harris and Rowland, 2001).
