Broadband Ground-Motion Simulation Using a Hybrid Approach
Robert W. Graves,Arben Pitarka +1 more
TL;DR: In this paper, a hybrid broadband ground-motion simulation methodology was proposed, which combines a deterministic approach at low frequencies ( f 1 Hz) and incorporates spatial heterogeneity in slip, rupture speed, and rise time.
Journal ArticleDOI
3D Elastic Finite-Difference Modeling of Seismic Motion Using Staggered Grids with Nonuniform Spacing
TL;DR: In this article, the authors proposed a technique to model seismic motions in 3D elastic media using fourth-order staggered-grid finite-difference operators implemented on a mesh with non-uniform grid spacing.
Journal ArticleDOI
Three-dimensional simulation of the near-fault ground motion for the 1995 Hyogo-Ken Nanbu (Kobe), Japan, earthquake
TL;DR: In this article, a 3D finite-difference method was used to simulate the near-fault ground motion from the 17 January 1995 Hyogo-ken Nanbu earthquake based on a kinematic fault model and a simplified 3D velocity structure.
Journal ArticleDOI
Ground-motion amplification in the Santa Monica area: Effects of shallow basin-edge structure
TL;DR: In this paper, the authors used 2D finite-difference ground-motion simulations to investigate the effect of the basin-edge structure in amplifying ground response in the 1994 Northridge earthquake.

Ely,Yoshihiro Kaneko,Y. Kase,Nadia Lapusta,Yajing Liu,Shuo Ma,David D. Oglesby,Kim B. Olsen,Arben Pitarka,Seok Goo Song,E. Templeton +22 more
TL;DR: The Southern California Earthquake Center/U.S. Geological Surveys (SCEC/USGS) Dynamic Earthquake Rupture Code Verification Exercise as discussed by the authors was the first time that a broad and rigorous examination of numerous spontaneous rupture codes has been performed and the results produced by these codes are compared using Web-based tools.
