Permeability is a fundamental physical property governing the efficacy and rates of many geological processes. Our ability to measure or characterise the values and distributions of permeability attending geological processes is critical to many facets of geoscience. For example, in volcanic processes (e.g., magma transport, eruption) permeability can be created or destroyed, controlling the means, efficiency, and rates of outgassing and, thereby, affecting eruption style and intensity. Alternatively, permeability and permeability anisotropy of fault zone structures are of paramount importance to fluid flow in the lithosphere, controlling crustal pore pressures and seismicity along major shallow or deep lithospheric structures. Outstanding and critical challenges for our science include evaluating permeability at geological conditions and understanding the evolution (e.g., creation or destruction) of permeability with the extent of processes and as a function of time/strain/stress. Here, we invite field-, experimental-, and model-based studies that inform on, or concern, the evolution of permeability influencing geological processes. Our intent is to foster strong interactions between research groups by soliciting contributions from diverse subdisciplines including (but not limited to) volcanology, rock and magma mechanics and physics, petrology, structural geology, and geophysics. We particularly welcome abstracts from early career scientists.
