My daughter goes to UC Santa Cruz. They have exceptionally well-preserved uplifting marine terraces there. There was a paper or 2 after 1989 Loma Prieta earthquake that compared the uplift of the coast there during the quake to long term uplift rate and came up with a recurrence interval for Loma Prieta oblique-slip quakes. I forget how often, but less often than one would expect for San Andreas quakes there. The problem could be that the terraces are well-preserved and uplifting, so you are placing a load on the crust (tectonic load), and the crust will sink a little into the mantle (isostacy, like putting more people into a rowboat). So, the terraces may sink a little between earthquakes. So, need more earthquakes to get the net uplift. This could probably be tested with continuous GPS, although the rates are so small that it might take 10 years to see (GPS is less precise on vertical, and rates are, I think, in the tenths of mm/yr).

I am about to resubmit my long-suffering Palos Verdes manuscript that discusses the same idea...today or tomorrow.
