Description:
Efficient and accurate hydrothermal and mechanical mathematical models in porous
media constitute a fundamental tool for improving the understanding of the
subsurface dynamics in volcanic areas. We propose a finite-difference ghost-point
method for the numerical solution of thermo-poroelastic and gravity change
equations. The main aim of this work is to study how the thermo-poroelastic solutions
vary in a realistic description of a specific volcanic region, focusing on the topography
and the heterogeneous structure of Campi Flegrei (CF) caldera (Italy). Our numerical
approach provides the opportunity to explore different model configurations that
cannot be taken into account using standard analytical models. Since the physics of
the investigated hydrothermal system is similar to any saturated reservoir, such as oil
fields or CO2 reservoirs produced by sequestration, the model is generally applicable
to the monitoring and interpretation of both deformation and gravity changes
induced by other geophysical hazards that pose a risk to human activity.
