Chris,

Thank you so much for this. Good read. Although I don't have your background and expertise in this, I must say I've picked up enough to also notice what you are saying. Indeed this activity is extending well into Riverside County and away from the initial vertical rupture line of the initial quake. This is my FIRST 7 quake to observe in real time in Southern California, however I have run a google map catalog of Loma Prieta (a 7.1 so comparable) and found that those aftershocks stayed strictly on the San ANdreas on the segment that ruptured. I.E. there was no migration 50 miles to the north on to the Hayward and Calaveras faults like there are to the Elsinore and San Jacinto.

If I HAD TO GUESS....I'm guessing this: THere indeed is going to be at least 2 maybe more additional major quakes out of this. If I had to guess when??? I'd say not soon, but either in the next year, but maybe as long as next 10. I'm sure we'll see a 6.5+ on San Jacinto, another 6.5 (or up to 7.2 if it ruptures all the way up through the OC and towards LA)on Elsinore and then maybe the long awaited 7.5+ on San Andreas. So within next ten to 15 years I see thats the area this will play out-and that this quake is the beginning of this process, similar to how Joshua Tree proceeded Landers, Big Bear and Hector Mine of the 90s.
