The THUMS-Huntington Beach fault branches from the Palos Verdes fault zone and south of that point forms the southwestern border of the Wilmington and Huntington Beach anticlines. Wilmington and Huntington Beach oil fields are located nearby, with timing and trapping mechanisms closely related to the evolution of the California Continental Borderland. The T-HBF, being part of Inner Borderland, is associated with change in vector of regional stress. Previously, this fault has been interpreted as a discontinuous feature. Correlation of newly acquired 2-D and existing industry 2-D and 3-D seismic and well data made it possible to identify that this is a right-slip fault zone with three segments. The T-HBF is striking northwest and has an average dip of 75° to the northeast. Wilmington and Huntington Beach anticlines are inverted basins formed as structural lows and then uplifted as a result of T-HBF activity in late Miocene-early Pliocene time.
