I don't consider the part of the fault between the equator and the 7.9 a "patch" on an unruptured fault...it would be more of a gap that did not rupture at all. Sure, parts that ruptured but did not slip much could have quakes...but could they rupture through the parts that slipped a lot? Or, might there not be a reason that they did not slip much...like the shear stress was not enough? They certainly got a strong trigger of a propagating rupture...so what is going to fire them off again?

To turn your earlier question around, do you have examples of large (say, M7 + quakes on strike-slip faults or M8+ on subduction quakes occurring within a couple of years on faults that had previously broken (within a few years...or even a decade or 2?).

To those non-earth scientists...this is sort of interesting: a geologist's perspective (where quakes are sort of a hobby, although I work with active faults), and a seismologist's perspective, who works more directly on these issues.
