I tried to Google this after checking the IRIS site, and did not find a source model or static stress diagram either. The linked IRIS site has an animation of aftershocks, which needs Quicktime which I don't have on this computer (guess I get it). It also has some displays of seismicity on maps with the projection center being the Baja quake. A few years ago we had discussions on this page about Far Field aftershocks being at certain angular distances from a quake. I think the idea was Lowell Whiteside's. Roger did some plots and it was unclear whether there was an effect; there was not a strong effect at least.
