Imaging, Modeling and Assimilation in Seismology Chapter uri icon

abstract

  • This chapter illuminates an emerging trend in earthquake ground-motion simulations. In this trend, earthquake sources are characterized by spontaneous rupture models and high performance computing systems are used to calculate time histories of ground motion with frequency contents up to several Hz in seismically active regions such as Southern California. We first review the basics of spontaneous rupture models. Then, a finite element method (FEM) algorithmEQdyna is introduced and two examples of ground-motion related applications are discussed. Finally, recent development of the FEM algorithm in parallelization using a hybrid MPI/OpenMP approach and its application to the convergence test of a benchmark problem are presented. 2012 Higher Education Press and Walter de Gruyter GmbH & Co.
