This isn't really anywhere near the junction - about 40 miles as the crow flies - so you don't have to be worried about it unlocking the Garlock/San Andreas.

It is not even on the Garlock - I don't think its on any currrently known fault ? Its near the White Wolf fault.

What I think is a bit odd is how its been working up o the bigger ones - its been swarming now since about Dec 18th I think and is going from smaller to now this 4.2 which has been the largest one in the series.
