New SCEC CFM Fault Areas/Major Boundaries
Southern Frontal & Channel Islands fault systems. These include the generally E-W-striking reverse, oblique-reverse and strike-slip faults that bound the northern LA basin, southern Santa Monica Mts and Northern Channel Islands, and would include onshore faults (e.g., Raymond, Hollywood, Santa Monica, & Malibu Coast faults), and faults that extend offshore across the Northern Channel Islands (e.g., Anacapa-Dume, Santa Cruz Island, Santa Rosa Island, Channel Islands thrust, etc).
