Let me tell you something about earthquakes. When the Coalinga quake occurred a couple of years ago, a lot of things were discovered. Houses that were built and were bolted to their foundation withstood that 8.2-on-the-Richter-Scale quake. The structure would go like this, but if it was bolted to the foundation, it withstood.

Now on the other hand, the houses that were built in a period when they did not bolt them to the foundation--again, a perfectly good house--when the horizontal earth movement occurred, the house moved maybe six or seven inches off its foundation. And that's what caused the house to collapse.

And so that was a great discovery made at Coalinga: Houses should be bolted to their foundation. It's not only on the foundation, but if you're going to add horizontal earth movement to this terrifying portrayal that we all face, then you need to have the house bolted into its foundation. Sort of a living relationship with the foundation--into it as well as on it.
