Hi Canie. I was able to find a little more about stress transfer from the Hector Mine quake. There isn’t much referred to the San Andreas fault except to say nothing has been seen. Take Care…Don in creepy town

Although we expect the final, refined solution to differ somewhat from the preliminary results shown in Figure 9, the preliminary solution is considered a robust estimate of the coseismic displacements across southern California. Significant co-seismic displacements were observed at stations as distant as Blythe and Palomar, and of course throughout the Mojave Desert region. The largest motion occurred at Landers Elementary School - that site has permanently shifted 19 cm towards the north- northeast. The static displacements from these rather far off sites are consistent with very simple uniform-slip dislocation models. As of this writing, post-seismic motions are only now beginning to creep above the few-millimeter noise level in SCIGN's daily measurements, at some of the nearest stations. No anomalous motions of stations along the San Andreas or other neighboring faults have yet to be observed by SCIGN, though these data will certainly be analyzed carefully for any indications of strain field changes induced by this earthquake.
