  A general-purpose model combining concepts from rational continuum mechanics,
fracture and damage mechanics, plasticity, and poromechanics is devised in
Eulerian coordinates, involving objective time derivatives. The model complies
with mass, momentum, and energy conservation as well as entropy inequality and
objectivity. It is devised to cover many diverse phenomena, specifically
rupture of existing lithospheric faults, tectonic earthquakes, generation and
propagation of seismic waves, birth of new tectonic faults, or volcanic
activity, aseismic creep, folding of rocks, aging of rocks, long-distance
saturated water transport and flow in poroelastic rocks, melting of rocks and
formation of magma chambers, or solidification of magma.
