Its not just Bombay... Its really whatever is under the most strain along the san andreas system...which can be a lot of places in Southern Cal - from offshore to nevada border and as far north as Coso Junction... and everywhere between.

A lot of people think the San Andreas is that one little line - but its not - the fault system includes many of the parallel faults in the area like Elsinore, Newport-Inglewood, San Jacinto, Banning, Lavic Lake, etc...Its the boundary between North American and Pacific Plates.
