Methane Seep Distribution in the Cascadia Subduction Zone
Figure showing the subsurface structure of the outer arc high (OAH) in (A) uninterpreted, (B) interpreted migrated industry seismic profile. The OAH in this region forms a broad structural high (10s of km wide) comprised of numerous imbricated thrust faults and associated folds. The OAH bounds the seaward edge of the forearc basin. The seafloor multiple is…
