Federal Plan for Natural Disaster Warning and Preparedness: First Supplement (FY1976-1980) [open pdf - 19MB]
From the foreword: "Natural hazards, such as the massive outbreak of killer tornadoes which struck 13 states early in April 1974, remain an ever-present threat to our Nation's welfare. Disaster surveys have indicated that the Nation's warning and preparedness system has reduced the toll in deaths, injuries, and economic losses from such hazards. However, unmet needs still exist in our monitoring, warning preparation, warning dissemination, and preparedness capabilities. The 'Federal Plan for Natural Disaster Warning and Preparedness' was published in June 1973. That Plan presented a comprehensive picture of the coordinated plans of 10 Federal agencies to bring about needed improvements to the warning system and preparedness programs. In the months since the Plan was prepared, much progress has been made to improve the system, and applications of recent technological advances promise even greater future improvements."
