Numerical simulation of lava flows based on depth-averaged equations
Antonio Costa, Giovanni Macedonio
Risks and damages associated with lava flows propagation (for instance the most recent Etna eruptions) require a quantitative description of this phenomenon and a reliable forecast…

Nonlinear phenomena in fluids with temperature-dependent viscosity: an hysteresis model for magma flow in conduits
Antonio Costa, Giovanni Macedonio
Magma viscosity is strongly temperature-dependent. When hot magma flows in a conduit, heat is lost through the walls and the temperature decreases along the flow causing a viscosit…
