Abstract:
Provides an authoritative overview of the role which computers now play in the field of seismology and discusses ways in which they can be improved for solving the increasingly complex problems now facing the scientist and engineer. Topics covered include typical seismic models, computational requirements associated with several standard numerical modelling techniques, three-dimensional processing, migration and forward modelling, advances in both hardware and software, iterative modelling, hypercube supercomputing, reservoir simulation using supercomputers, algorithms used in modelling and i.
