Seismic source mechanisms for quarry blasts:

Jan 01, 2004  The method of elastic finite differences with recursive grid refinement (see McLaughlin Day 1994) was used to model 3-D wave propagation in this problem with a large range of scales. The quarry was modelled with a fine grid of 5 m cells enclosed in a succession of coarser grids as illustrated in Fig. 7. Eight levels of refinement were used ...
