I have a USGS report online on offshore faults including a wider fault zone that includes the Newport-Inglewood (see link; I linked this about last June). I just did a partial draft of a SCEC proposal lastw eek for HW to finish and submit for some funding for a student. The Newport-Inglewood-Rose Canyon fault runs along the middle of the narrow Continental Shelf, while the upper edge of a moderately NE-dipping San Mateo-Carlsbad fault is beneath the base of the Continental Slope. But, these 2 faults, which project to intersect at depth, partially merge from near San Clemente until it comes ashore near Newport Beach. So, for this 20 km (?)-long offshore stretch, you might get a little thrust along with your right-lateral. The long-term rate just on the San Mateo-Carlsbad is about 1 mm/yr, plus whatever is on the Newport Inglewood. A couple of decades ago Tom Rockwell did one of his famous 3D trenched across the Rose Canyon in San Diego and it was 2 mm/yr right-lateral during some part of Holocene (last 8000 years?). And, there is more farther offshore on the Descanso fault that we mapped.
