I woke up early so am wasting time before I submit an AGU abstract on the earliest West Antarctic ice sheets (before 14 million years ago and after about 25). Some of you may be interested in 3 SCEC abstracts that I wrote (with co-authors). One is on the Santa Monica-Dume and Malibu Coast faults, and the right-lateral faults that terminate against it. We model that there has been 6 +5/-1 km of left-lateral slip on this fault in the last 4 +/-1 million years. Adding the modeled slip on the Malibu Coast fault, which has been oblique-left reverse onshore, gives about 9 km of left slip and several of reverse slip on the onshore Santa Monica fault (Malibu Coast fault merges with it). There is good reason to think that this long-term slip rate is applicable to today. Active right-lateral faults, the San Pedro Basin fault and Palos Verdes fault, terminate into or near the left-lateral faults....but do not much disrupt the left-lateral faults. This is because much of their slip is absorbed by clockwise rotating blocks (viewed looking down). One of several strands of the northern Palos Verdes fault coincides with disrupted submarine ravines just below the shelf break, near and north of Santa Monica Canyon.

Another is on offshore evidence for the Compton thrust...this email is already getting too long, but we see that the SW limb of the fold responsible for the Palos Verdes Hills is straight and continuous for 45 km, and then changes character beyond a "step" and continues another 10 km to the SE...and that this is folding above NE-dipping blind faults that project in 3D into the controversial Compton thrust from the SCEC Community Fault model (work with K.B., now in the oil patch, and others). I think the Compton thrust exists, and is at least potentially active, but its geometry and extent is different than published.

The last, with C.N., suggests that GPS data in parts of California with deep sedimentary basins cannot be evaluated properly without basin modeling....that, especially for Ventura basin, part of the measured horizontal shortening is related to sediment compaction and that therefore accumulation of elastic strain (related to how often you expect large earthquakes) is overestimated there (could be by 10s of percent) and underestimated elsewhere.
