Summary on Grant Application Form
Brittle failure of a material will generate seismic energy which will propagate through the material away from the fracture. If fluids are present electromagnetic energy will also be generated, and may be detected some distance away from the source. This project will develop 3D finite-difference code to investigate the propagation of seismic and electromagnetic energy away from a fracture source. Understanding fluid flow in fractures and porous rock is of importance in many different fields. The detection of fracture damage around underground mine workings and excavations and the capability to detect the presence of fluid within these fractures is paramount to understanding their stability. A 48 node supercomputer will be built in collaboration with Prof Hank Dietz, Kentucky University, USA. Existing finite-difference code will be modified to run on this computer, and will enable the solution of 'site scale' propagation of both seismic and electromagnetic energy at sufficient resolution to include a fluid filled fracture source. The project objective is to understand the propagation of seismic and electromagnetic energy away from a fracture source in a realistic subsurface environment, and to understand how best to instrument a site to monitor brittle failure and the movement of fluids. The emergence of new and affordable computing technology makes this possible for the first time.
