Summary Numerical simulations of earthquakes and seismic wave propagation require accurate material models the solid Earth. In contrast to purely elastic rheology, poroelasticity accounts for pore fluid pressure flow in porous media. Poroelastic effects can alter both field dynamic rupture characteristics earthquakes. For example, presence fluids may affect cascading multi-fault ruptures, potentially leading larger-than-expected However, incorporating poroelastic coupling into elastodynamic...
SUMMARY We present a discrete representation of strongly heterogeneous poroelastic medium with the JKD-model frequency-dependent permeability and resistive friction, corresponding finite-difference (FD) scheme for numerical modelling seismic wave propagation earthquake ground motion in structurally complex media. The is capable subcell resolution, that is, allows an arbitrary shape position interface spatial grid. can have either zero friction or non-zero constant JKD friction. has same...
ABSTRACT By analyzing the equations of motion and constitutive relations in wavenumber domain, we gain important insight into attributes determining accuracy finite-difference (FD) schemes. We present heterogeneous formulations for four configurations a wavefield an elastic isotropic medium. Fourier-transform entire to domain. Subsequently, apply band-limited inverse Fourier transform back space analyze consequences spatial discretization band limitation. The heterogeneity medium...
SUMMARY We present a new methodology of the finite-difference (FD) modelling seismic wave propagation in strongly heterogeneous medium composed poroelastic (P) and (strictly) elastic (E) parts. The can include P/P, P/E E/E material interfaces arbitrary shapes. part be with (i) zero resistive friction, (ii) non-zero constant friction or (iii) JKD model frequency-dependent permeability friction. Our FD scheme is capable subcell resolution: interface have an position spatial grid. keeps...
