Here, this might help you folks in California:
SOPAC - Southern Pacific Tectonics, USGS WCMG
The San Andreas is the boundary between the North American and Pacific tectonic plates. See the little red circle on the map in the link? That's right about where this quake occurred. It's a boundary between three interacting plates - the North American, the Nazca and the Antarctic. All moving in different directions at different speeds. Which helps push up the Andes, creates some of the word's more active volcanoes and also makes the ground shake on a regular basis.
Not only is there no connection between the San Andreas and the fault systems there, but the area doesn't even interact with the same tectonic plates. In other words, the motion is different, the cause is different and there is no relationship between events in California and Southern Chile.
Hope that helps a little?

Yeah man, I'm sure the 1906 earthquakes were just a huge coincidence.
But living in San Francisco, you really shouldn't need an earthquake that happens half way around the world, to prompt newfound preparedness.
