It's kind of fun to pretend to understand which cog or stress point will break next, and we can make some guesses based on what little history we really have of the process.
I think we do understand it enough to know where the major faults are, and the biggest fault line is the San Andreas running from east of Los Angeles to a point somewhat north of San Francisco. No news to anyone here.
It's going to keep chugging along and breaking as long as any of us are alive, and for quite awhile afterward.
Using GPS systems, satellite data, ground data, geologic history and computer models I think we will be able to reach a point where we can predict earthquakes with some certainty.
