文摘
We seismically image fracture zones in the terranes of the Cascadia forearc. The extent of fractures controls the permeability properties of the forearc. This extent also determines the presence of shallow non-volcanic tremors. Variations of pore-fluid pressure explain the segmentation of frictional behavior.
