[图书][B] The finite-difference modelling of earthquake motions: Waves and ruptures

P Moczo, J Kristek, M Gális - 2014 - books.google.com
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 …

Full‐3‐D tomography for crustal structure in southern California based on the scattering‐integral and the adjoint‐wavefield methods

EJ Lee, P Chen, TH Jordan… - Journal of …, 2014 - Wiley Online Library
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 …

Site amplification in the Los Angeles basin from three-dimensional modeling of ground motion

KB Olsen - Bulletin of the Seismological Society of …, 2000 - pubs.geoscienceworld.org
It is well established that sedimentary basins can significantly amplify earthquake ground
motion. However, the amplification at any given site can vary with earthquake location. To …

Strong shaking in Los Angeles expected from southern San Andreas earthquake

KB Olsen, SM Day, JB Minster, Y Cui… - Geophysical …, 2006 - Wiley Online Library
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 …

Full 3D tomography for the crustal structure of the Los Angeles region

P Chen, L Zhao, TH Jordan - Bulletin of the …, 2007 - pubs.geoscienceworld.org
We apply full 3D tomography (f3dt) to a regional dataset in the Los Angeles area. In f3dt, the
starting model as well as the model perturbation is three-dimensional and the sensitivity …

Misfit criteria for quantitative comparison of seismograms

M Kristeková, J Kristek, P Moczo… - Bulletin of the …, 2006 - pubs.geoscienceworld.org
We have developed and numerically tested quantitative misfit criteria for comparison of
seismograms. The misfit criteria are based on the time-frequency representation of the …

Modeling dynamic rupture in a 3D earthquake fault model

R Madariaga, K Olsen… - Bulletin of the …, 1998 - pubs.geoscienceworld.org
We propose a fourth-order staggered-grid finite-difference method to study dynamic faulting
in three dimensions. The method uses an implementation of the boundary conditions on the …

Estimation of Q for Long-Period (>2 sec) Waves in the Los Angeles Basin

KB Olsen, SM Day, CR Bradley - Bulletin of the …, 2003 - pubs.geoscienceworld.org
Abstract We simulate 0-to 0.5-Hz 3D wave propagation through the Southern California
Earthquake Center seismic velocity reference model, version 2, for the 1994 Northridge …

Hybrid Broadband Ground-Motion Simulations: Combining Long-Period Deterministic Synthetics with High-Frequency Multiple S-to-S Backscattering

PM Mai, W Imperatori, KB Olsen - Bulletin of the …, 2010 - pubs.geoscienceworld.org
We present a new approach for computing broadband (0–10 Hz) synthetic seismograms by
combining high-frequency (HF) scattering with low-frequency (LF) deterministic …

Scalable earthquake simulation on petascale supercomputers

Y Cui, KB Olsen, TH Jordan, K Lee… - SC'10: Proceedings …, 2010 - ieeexplore.ieee.org
Petascale simulations are needed to understand the rupture and wave dynamics of the
largest earthquakes at shaking frequencies required to engineer safe structures (> 1 Hz) …
