Query: A monolithic model for phase-field fracture and waves in solid-fluid
  media towards earthquakes   Coupling of rupture processes in solids with waves also propagating in fluids
is a prominent phenomenon arising during tectonic earthquakes. It is executed
here in a single `monolithic' model which can asymptotically capture both
damageable solids (rocks) and (visco-)elastic fluids (outer core or oceans).
Both ruptures on pre-existing lithospheric faults and a birth of new faults in
compact rocks are covered by this model, together with emission and propagation
of seismic waves, including, e.g., reflection of S-waves and refraction of
P-waves on the solid-fluid interfaces. A robust, energy conserving, and
convergent staggered FEM discretisation is devised. Using a rather simplified
variant of such models for rupture, three computational experiments documenting
the applicability of this approach are presented. Some extensions of the model
towards more realistic geophysical modelling are outlined, too.
