Seismic mapping indicates that Lasuen Knoll in the Inner Borderland, offshore southern California, is a pop-up structure associated with a restraining stepover of the Palos Verdes Fault. Dextral shear is apparently transferred southeast through a complex zone of faults that includes the Carlsbad Ridge and Coronado Bank faults. This model is supported by comparison with other pop-up structures in the Inner Borderland and analogs to published sandpack laboratory simulations.
The Palos Verdes Fault along Lasuen Knoll has existed at least since the late Miocene Epoch (5 to 8 Ma) and is contemporaneous with the segment of the Palos Verdes...
