Canie..I just in last half hour compared the seismic reflection profiles to a cross section (G-G' in Wright 1991, detail in his Fig 13, and my younger horizon is top Lower Pico (1.8 Ma in Blake 1991, same volume) (Ma is million years old). The folding near the Palos Verdes fault is older than this I think (have to look at data longer than a couple days), but the southern continuations of the San Pedro escarpment did not start folding until 1.8 Ma...so younger than I expected, which means it is likely that the faults that created the folds are still active (a bit of a leap there, but likely). I have not looked at data for a big stretch between the area just south of San Pedro Shelf and Oceanside (I did work south of Oceanside offshore), but it is likely that the young folding and thrusting I see if related to the folding and thrusting of the Oceanside thrust of Rivero, Shaw, Mueller (Geology), which may be the fault system related to the uplift seen by Grant et al (your link). Neither the Oceanside thrust nor the Compton thrust were in the USGS/state (??) hazard models...I made a noise at a meeting at the 2005 SCEC meeting that removing the Compton thrust was a mistake. As for whether I am mapping new faults....faults had been interpreted before along the base of the San Pedro escarpment, but I am not aware of anyone interpreting NE-dipping thrust fault tips there, and relating these faults to the Palos Verdes anticlinorium. There are parts of this fault system that I am mapping that probably have not been mapped by academics before...oil industry probably mapped everything in 1970s and 1980s, so we are only 3 decades behind...But the oil industry is capable of fouling up interpretations (although maybe not on 3D data), as are academics (not me, of course...(joking).
My April 2006 SSA abstract looks pretty good....making certain assumptions (subsidence rate, dip of fault), I said 2 mm/yr slip on the blind fault. If ut goes in pieces...in M6.5 quakes with 1 m of slip, it would take 500 years to load any one piece. If it all goes in a big quake >M7, then it might slip several meters and take thousands of years to repeat...

Hey, my Journal of Geophysical paper on the Santa Monica-Dume-Malibu Coast fault came out this month....
