Abstract
This article estimates the ground motion during the January 26, 2001 Gujarat, India earthquake by spectral finite element method. The SPECFEM3D_GLOBE package which models the complete three-dimensional wave velocity structure, ellipticity, topography, and bathymetry is used to simulate the ground motion on a global scale. The Earth is modelled with 553.4 million grid points. Displacement time histories are simulated at various stations in the epicentral region. A contour map of permanent ground displacements in the near source region is provided. The obtained results are validated by comparing them with recorded peak ground velocity data and field observations.
