I've generated a map comparing current activity since the beginning of the month (April 2014) against the Hauksson relocated catalog.
The area has had quakes in the past, and it's obvious from the distribution that there are small branches or filaments of faults in the area.
They run generally parallel to the San Jacinto Fault Zone with runs SE to NW as seen on the right of this image.
Obviously the current USGS locations are rough but the distribution almost appears to make this current activity on a cross fault.
However, I suspect relocation would put things 'straight'.
