EISBN: 9781862399587
... Abstract The MAGFLOW model for lava-flow simulations is based on the cellular automaton (CA) approach, and uses a physical model for the thermal and rheological evolution of the flowing lava. We discuss the potential of MAGFLOW to improve our understanding of the dynamics of lava-flow...

... the HOTSAT volcano hotspot detection system, which works with satellite thermal infrared data, and the MAGFLOW lava flow emplacement model, which is able to relate the flow evolution to eruption conditions at the vent. We used HOTSAT to analyze Moderate Resolution Imaging Spectroradiometer (MODIS...

..., and the inclusion of tools to produce different scenarios as eruptive conditions change, is a major challenge in volcanic hazard assessment and is increasingly solicited by local authorities responsible for volcanic risk mitigation ( Del Negro et al. 2013 ). Thus HOTSAT has been integrated with the MAGFLOW...

... underlies significant population centres, including Clermont Ferrand, central France’s main city. Simulations were completed through implementation of six lava-flow emplacement models: MAGFLOW, LavaSIM, SCIARA, VolcFlow, DOWNFLOW and FLOWGO (see Appendix B of this Special Publication ( Harris et al...

.... This section presents simulations results as a guideline for some of the benchmarks described previously (BM1 and CCTC1). BM1 was tested with the codes VOLCFLOW (K. Kelfoun), FLOW3D (E. Lev), OPENFOAM (E. Lev) and NB3D (B. Cordonnier); CCTC1 with DOWNFLOW (M. Favalli), FLOWGO (A. Harris), MAGFLOW (C. Del...

... investigation based on fluid dynamics. Near-real-time determination of the effusion rate during an ongoing volcanic effusive crisis is crucial for estimating ensuing lava inundation and for planning evacuation. For example, recent fast-computing models of lava-flow advance, such as MAGFLOW ( Del Negro et al...

...-front arrival time at specified (sensitive) locations. More complex models such as SCIARA ( Crisci et al. 2004 ), LavaSIM ( Hidaka et al. 2005 ) and MAGFLOW ( Vicari et al. 2007 ) are better suited to such applications. However, we quickly realized that FLOWGO’s stopping condition for the channel...
