Project Description
The software package SPECFEM3D_GLOBE simulates global and regional (continental-scale) seismic wave propagation. Effects due to lateral variations in compressional-wave speed, shear-wave speed, density, a 3-D crustal model, ellipticity, topography and bathymetry, the oceans, rotation, and self-gravitation are all included. Recent new features include full 21-parameter anisotropy and lateral variations in attenuation.
