Thermal and pore-pressure variations induced by the circulation of hydrothermal-magmatic fluids in porous permeable media contribute to ground deformation volcanic areas. Here, we use solutions for calculation displacements temperature changes simplified geometry sources embedded an elastic half-space with homogeneous mechanical properties. The analytical solution a spherical source is reviewed, semi-analytical approach displacement cylindrical presented. Both models were used inversion...
Abstract Volcano-hydrothermal systems are governed by complex interactions between fluid transport, and geochemical mechanical processes. Evidence of this close interplay has been testified distinct spatial temporal correlations in geophysical observations at Vulcano Island (Italy). To understand the interaction circulation manifestations, we perform a parametric study to explore different scenarios implementing hydro-geophysical model based on equations for heat mass transfer porous medium...
When approximating elliptic problems by using specialized approximation techniques, we obtain large structured matrices whose analysis provides information on the stability of method. Here provide spectral and norm estimates for matrix sequences arising from Laplacian via ad hoc finite differences. The involves several tools theory in particular setting Toeplitz operators Generalized Locally sequences. Several numerical experiments are conducted, which confirm correctness theoretical findings.
