The role of rock fractures at all scales is fundamental to understanding the mechanical strength of rock, the stability of underground openings, and the flow of fluids through discrete fracture networks. New insights are coming from detecting, monitoring, and processing micro-seismic events in geothermal systems, hydrofracking, glaciers, sedimentary basins, and seismically “dead” areas. The spatial and temporal properties and patterns of fractures are nonlinear and typically scale invariant. This session welcomes abstracts from those conducting research on fracture analysis and/or detection methods, fracture initiation and growth, fracture strength, and the ability of discrete fracture networks to conduct fluid flow over scales ranging from nanometers to the regional scale. We welcome abstracts from those analyzing or observing rock fractures and fracture dynamics in the laboratory, in the field, and through numerical modeling.
