Lavadest

Lavadest is a term used in volcanology to describe an integrated framework for forecasting the path and destination of lava flows during eruptions. It combines real-time field observations, topographic data, and rheological models to produce probabilistic predictions of where lava is most likely to travel and how much may be emitted.

Core components include geographic information system data, thermal imaging, seismic signals, and numerical models of lava flow, such as cellular automata and physics-based simulations. Outputs typically consist of hazard maps with probability levels assigned to landscape cells, estimated lava volumes, and recommended risk-reduction measures. The approach emphasizes uncertainty quantification and scenario planning to aid emergency management and land-use decisions.

Historically, the concept emerged as part of broader efforts to improve volcanic hazard assessment in the 2010s. It has since been refined by researchers and integrated into regional monitoring programs at several active volcanoes, with variants adapted to different eruption styles and resource constraints.

Limitations include dependency on input data quality and the extent to which models capture lava rheology, eruption rate, and boundary conditions. Rapid changes in eruption behavior or topographic modification can reduce forecast reliability. As with any forecast, lavadest results are probabilistic and should be used alongside direct observations and authoritative guidance.
