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 …

This review article revisits and outlines the perfectly matched layer (PML) method and its
various formulations developed over the past 25 years for the numerical modeling and …

Full-wavefield seismic inversion (FWI) estimates a subsurface elastic model by iteratively
minimizing the difference between observed and simulated data. This process is extremely …

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 …

We have successfully applied full‐3‐D tomography (F3DT) based on a combination of the
scattering‐integral method (SI‐F3DT) and the adjoint‐wavefield method (AW‐F3DT) to …

In this study, we propose a new numerical method, named as Traction Image method, to
accurately and efficiently implement the traction-free boundary conditions in finite difference …

The complex-frequency-shifted perfectly matched layer (CFS-PML) technique can efficiently
absorb near-grazing incident waves. In seismic wave modeling, CFS-PML has been …

The southernmost San Andreas fault has a high probability of rupturing in a large (greater
than magnitude 7.5) earthquake sometime during the next few decades. New simulations …

We present a new method for calculating broadband time histories of ground motion based
on a hybrid low-frequency/high-frequency approach with correlated source parameters …

Perfectly matched layers (PMLs) provide an exponential decay, independent of the
frequency, of any propagating field along an assigned direction without producing spurious …
