Scale-dependent wear and re-roughening processes in a single fault zone
MetadataShow full item record
One factor that exerts a major control on earthquake source parameters is the geometry of a fault zone. Observations previously compiled from multiple faults show that fault surface shape evolves with displacement. The specific processes driving fault evolution within a single fault zone and their influence on fault geometry are not well known. Here, we characterize the deformation history and geometry of an extraordinarily well-exposed fault using maps constructed with the Structure from Motion photogrammetric method. The geometry of cross sectional traces of contacts of different relative age ...
