The tornadoes last week in Arkansas killed about as many people as Northridge or Loma Prieta, yet likely will be forgotten a year from now, whereas Northridge and Loma Prieta have influenced, and will continue to influence, codes for years to come, and jack up construction and design costs in the process. In this century, at least several times more deaths have been caused by tornadoes and hurricanes than by earthquakes, yet the bulk of the research on natural hazards mitigation in recent years have been on earthquakes. And, of course, lets not forget the increased costs for seismic-related design time, structural observations, etc., by design professionals. On a where-are-the-bodies test with respect to public safety, seismic design should command much less construction and design resources than it now gets. BTW, I lifted the question from my wife, a chemist and industrial hygienist who is a veteran of battles with NIMBYs and no-growthers who foment paranoia over the effects of minute traces of 'toxic' chemicals in the environment. When they raise the safety issue for the umpteenth time at public hearings, she on several occasions lost her cool and countered with the politically incorrect, but valid, question. It's equally valid to ask of code writers and design professionals. Frank Lew, SE Orinda, CA
