Journal ArticleDOI
Viscoelastic finite-difference modeling
TL;DR: In this article, a finite-difference simulator was developed to model wave propagation in viscoelastic media, and a staggered scheme of second-order and fourth-order accuracy was proposed.
Journal ArticleDOI
Modeling of a constant Q; methodology and algorithm for an efficient and optimally inexpensive viscoelastic technique
TL;DR: In this article, the authors present a method for modeling constant Q as a function of frequency based on an explicit closed formula for calculation of the parameter fields, which enables substantial savings in computations and memory requirements.
Book ChapterDOI
The finite-difference time-domain method for modeling of seismic wave propagation
TL;DR: In this article, a review of the recent development in finite-difference time-domain modeling of seismic wave propagation and earthquake motion is presented, which is a robust numerical method applicable to structurally complex media.
Journal ArticleDOI
A numerical free-surface condition for elastic/viscoelastic finite-difference modeling in the presence of topography
TL;DR: In this paper, an elastic/viscoelastic flat horizontal free-surface condition is compared and benchmarked against an analytical solution, which is simple to implement in conventional staggered finite-difference schemes, is computationally efficient and enables modeling of highly irregular topography.
Journal ArticleDOI
Constraints on the shallow elastic and anelastic structure of Mars from InSight seismic data

TL;DR: In this paper, the authors measured the crustal diffusivity and intrinsic attenuation using multiscattering analysis and found that seismic attenuation is about three times larger than on the Moon, which suggests that the crust contains small amounts of volatiles.
