We present a review of the recent development in finite-difference time-domain modeling of
seismic wave propagation and earthquake motion. The finite-difference method is a robust …

Solving efficiently the wave equations involved in modeling acoustic, elastic or
electromagnetic wave propagation remains a challenge both for research and industry. To …

This article reports on the development of a modular two-step, finite-element methodology
for modeling earthquake ground motion in highly heterogeneous localized regions with …

We analyze the problem of a heterogeneous formulation of the equation of motion and
propose a new 3D fourth-order staggered-grid finite-difference (FD) scheme for modeling …

Among all the numerical methods in seismology, the finite-difference (FD) technique
provides the best balance of accuracy and computational efficiency. This book offers a …

The invitation by Vladimır Buzek to write a text that would present a topic of our research was
for us a strong motivating challenge and nice opportunity at the same time: we could and we …

We review key ingredients that are needed for high-fidelity simulation of earthquake-
generated seismic waves in large regions. Specifically, we survey existing literature on wave …

We present a set of methods for modeling wavefields in three dimensions with the acoustic-
wave equation. The primary applications of these modeling methods are the study of …

Realistic anelastic attenuation can be incorporated rigorously into finite difference and other
numerical wave propagation methods using internal or memory variables. The main …
