    Fluid-solid coupling drives the dynamic systems of volcanoes, earthquakes, and tsunamis. Magma-filled dikes propagate within active volcanoes. Megathrust earthquakes shift the seafloor and excite...

    A fluid-dynamic model is developed to numerically simulate the non-equilibrium dynamics of polydisperse gas-particle mixtures forming volcanic plumes. Starting from the three-dimensional N-phase Eulerian transport equations for a mixture of gases and solid particles, we adopt an asymptotic...

    A 2D non linear diffusion code is by Mattia de' Michieli Vitturi (Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Pisa).This code solve for the nonlinear diffusion problem dh/dt = div( f(h) grad(h) )wheref(h) = k * ( 1 + ( max_nlc -1 ) * ( |grad(h)| / S_c )^n )k is...

    PlumeMoM is a numerical code for the steady-state plume model, describing the rise in the atmosphere of a mixture of gas and volcanic ash during an eruption. The system of equation is formally the same of that presented in Barsotti et al. 2008, i.e. the equations we formulate describe the same...
