I can't tell what I am looking at with the GPS map either...they don't seem to make sense...you should see the sites east of the San Andreas moving to the SE and those west moving to the northwest. These maps usually have a reference frame...if the reference frame was set to North America, everything in SW California should move to the NW...with greater motion the farther southwest you go. I don't see that pattern. I guess I could figure it out if I spent a couple hours. For my work, it would be useful for me to be able to set a reference...for example, Make Santa Cruz Island the reference and see how Santa Barbara and Ventura are moving. Does anyone know if you can do this on this page?

Also...concerning Brad's 1996 and 2006 map...one thing I think I see is that the 2006 (red) quakes better define narrow lineaments in some cases...likely because the locations are better. In other areas, they define clouds still...this may be real...the quakes may for clouds. As for the shallow quakes in the sediments...I suppose is possible, but depths are often not accurate.
