Can't spit without hitting a California fault

Article

I assume the California crust is fully fractal-fractured. That means the closer you look, the more smaller and smaller faults you find. Does it mean anything?

"I think every classroom in California should have these maps on the wall," said Caltech seismologist Lucy Jones. "I don't think we do enough to educate the general public about these features. We turn it into something for the specialists, as if science is only for scientists. But if you're going to buy a house, would you like to know what fault is under your house?"

Ms. Jones seems to think so, and I'll believe anything she says! :)
