Abstract

The tornadoes of April 3-4, 1974 , affected eleven states and Canada, and killed more than 300 persons. This tornado outbreak was the most extensive and devastating in history in terms of property damage. Meteorologists have termed this tornado outbreak the most significant meteorological event of the last 50 years. Dr. Fujita of the Univeristy of Chicago and his staff have located 148 individual tornado tracks, all of which occurred in one 18 hour period. The meterological, engineering, and architectural professions were challenged to investigate and document the damage caused by the extensive tornado outbreak. The writers acting in collaboration with individuals from three other Universities and working under sponsorship of the Committee on Natural Disasters of the National Academy of Engineering have collected vast amounts of data on engineering aspects of the April 3-4 tornadoes. A preliminary report summarizing these data will be published by the National Academy of Sciences . A painstaking evaluation of the collected data is being developed under sponsorship of the National Severe Storms Laboratory and the Atomic Energy Commission . These evaluations can lead to recommendations for structural design that will mitigate effects of severe storms on society. (from paper)
