I remember Chris commenting on this article when it first came out. Along with his comments and further research I did I learned that this article is extremely inconclusive.

All we know for sure from it is that exact amount being compressed. What noone really knows for sure is what structure(s) accomodate for this compression. I.E. is it being accomodated fairly easily by several unknown blind thrust systems that are in free movement? Could the Sierra Madre Fault possibly be absorbing this strain? What unknown forces are accomodating this movement?

OR

None of the above. There are several blind faults that are absorbing the movement but not "accomodating" and are all waiting to go off with swarms of 6+ temblors to relieve it all. Could 1971 and 94 be the beginning of several decades of unrest in LA? It has been said that LA is on a quake deficit as we speak.

Unlike the Bay Area where scientists SEEM to have a handle on the hazards, noone in LA REALLY knows the true Hollywood story of what the true risk potential is. And if anyone would like to dispute that comment, I would love it, I have done so much research only to turn up ambiguous documents like the on above that suggest threats but don't go all the way to apply statistics or break it out as it has been done in San Francisco.
