- First, 8.3 is not "only a little" larger than Landers. It represents almost
- 30 times the energy of the Landers quake. In addition, the "Big One (TM)"
- will be closer to major population than Landers. Both of these factors will
- contribute to greater damage. I personally consider the damage and casualty
- estimates for the 8.3 to be over-estimated. However, I do not dispute this
- practice, it is important to err on the side of caution.
