Brian,
as you know, you are correct about it being a spreading center. It forms a very different kind of crust than a mid-ocean spreading center because of the very high sediment input.
Yes, I was thinking that it might be of more concern if the quakes were deeper, and away from what is presumably a hot, weak, and thinner crust.
On the other hand, how a future southern San Andreas quake might start is not likely to be known or understood.
