Numerical modeling of complex fault systems: implications for seismic hazard analysis and mineral exploration

Earthquake rupture simulations will improve seismic risk analysis by illuminating the controlling effect that fault-structures and material properties have on rupture propagation and on earthquake magnitude. Our results will also aid mineral exploration by describing the formation and evolution of fault structures suitable for mineral deposition.

The maximal earthquake magnitude expected to occur along a fault system is typically estimated according to the length of individual fault segments and the distance between fault-segments. This project will improve conventional seismic hazard analysis by describing how material and structural properties along and between fault-segments control earthquake rupture length and earthquake magnitude. Our results will provide practical tools for improved assessments of earthquake risk. In addition, simulations of evolving fault-material and structures will be used to identify conditions favorable for mineral deposition, and will aid in mineral exploration along fault-systems.
