According to the info on the SCEC site the recurrence interval is unknown, but the slip rate is .6mm per year. So that's only about 46 mm since 1933. Doesn't seem like enough to worry about.

However, there is the nearby parallel Palos Verde fault to the SW which may accommodate up to 3 mm per year, and has not ruptured in historical times.
