Chris, I forgot to share this link. Seems like a good thesis statement for the overall situation.

Thomas Rockwell;

"The historical seismicity, with M7-7.5 earthquakes on the LS, IF and CP faults during the past century, suggests that the area has entered another period of larger earthquake production, possibly leading to failure of the two largest fault zones, the south-central SJ and southern SA faults, each of which is capable of large earthquakes and neither of which have broken in about 300 years".

LS = Laguna Salada
IP = Imperial
CP = Cerro Prieto

All active with numerous non-conformity focal mechanisms at depth. He did point out the asperity in Anza. Because the 2D scatter is so prevalent across the Anza Seismic Gap, I believe the only data which will support precursor activity will be found in depth analysis. AMR does not work for Anza in 2D model because the data overwhelms any significant differentiation. It may be noticeable down the southern section of Elsinore into LS. (La Posta pluton)
