Nice little group of quakes in the Cajon Pass. Not quite placed on the San Andreas, but then these automatic solutions are never perfect, and the SA does have a slight dip if I recall correctly.

The focal mechanism is oblique reverse right-lateral . If the NW-SE nodal plane is the fault plane, it indeed dips NE and thus could be on or close to the San Andreas proper:

Bears watching.

No, not the mammal with teeth and claws.
