Seismic waves in medium with poroelastic/elastic interfaces: a two-dimensional P-SV finite-difference modelling
Geophysical Journal International(2021)
摘要
We present a new methodology of the finite-difference (FD) modelling of seismic wave propagation in a strongly heterogeneous medium composed of poroelastic (P) and (strictly) elastic (E) parts. The medium can include P/P, P/E and E/E material interfaces of arbitrary shapes. The poroelastic part can be with (i) zero resistive friction, (ii) non-zero constant resistive friction or (iii) JKD model of...
