🌋 Volcano Near a City: Lava Flow Routing, Ash Fall and Hazard Zoning Lab

A stratovolcano above a harbour town: lava spreads as a viscous gravity current (Jeffreys' law, Bingham yield, Gratz-limited cooling), a Mastin plume and Suzuki-type ash model load the roofs, and DOWNFLOW routing builds hazard zones with an abstract evacuation-time margin. Check the solver's front speed against Jeffreys' formula.
