There was just a M4.9 followed by a 4.5 right at the interection I mentioned, along the little circle of quakes, but not at its center. Possibly worth a seismologist (John V., Roger) taking a look at whether the small circle of tiny quakes is real and whether they think it at all significant. Regardless of whether the circle meant anything related to stress, the intersection of the NNE seismicity with the San Jacinto would still be a good place to keep an eye on for a larger quake...but that is kind of obvious and noticed by many.
