“…The description and interpretation of fault zone geometry, architecture and evolution are important for understanding and predicting the impact of faults on fluid flow in the upper crust, including groundwater flow (Bense and Van Balen, 2004;Bense and Person, 2006;Folch and Mas-Pla, 2008), hydrocarbon migration, entrapment and production (Grauls et al, 2002;Sorkhabi and Tsuji, 2005;Manzocchi et al, 2010;Wibberley et al, 2017), hydrothermal flow and mineralization (Rowland and Sibson, 2004;Person et al, 2008;Fairley 2009), nuclear waste storage (Ofoegbu et al, 2001;Gray et al, 2005), and CO 2 sequestration (Shipton et al, 2004;Agosta et al, 2008;Dockrill and Shipton, 2010). The internal structure of a fault zone may also affect its seismogenic behaviour (Sibson, 1986;Scholz, 2002;Sibson, 2003;Rice and Cocco, 2007).…”
