Envisioned a N-S trending transform fault (connecting two ridges, the Kula Pacific Ridge and the Philippine Ridge/Central Basin Fault as turning into a subduction (the proto-Mariana Trench) zone following a change in the Pacific Plate's motion from NNW to WNW during the Eocene. In this model, the basin is originally a part of the Pacific Plate which was isolated during the kinematic reorganization 43 Ma.

Formed behind a subduction zone and involves process that creates an extensional regime oriented perpendicular to the subduction zone. First proposed by Karig (1971), shows the WPB as forming by back-arc spreading behind the Oki-Daito Ridge starting the Eocene. Crustal extension within the plate took
