National Earthquake Hazards Reduction Program: Fiscal Year 1983 Activities, Report to the United States Congress [open pdf - 43MB]
From the Introduction: "The National Earthquake Hazards Reduction Program (NEHRP) was established by the United States Congress in 1977 to reduce the risks of life and property from future earthquakes in the United States. The Earthquake Hazards Reduction Act of 1977 (Public Law 95-124) directed the President 'to establish and maintain an effective earthquake hazards reduction program.' The Congress recognized that earthquakes pose perhaps the greatest single-event natural hazard faced by the Nation. An earthquake can affect hundreds of thousands of square miles, can cause damage to property measured in the tens of billions of dollars, can cause loss of life and injury to tens of thousands of persons, and can disrupt the social and economic function of the affected area, and potentially, of the entire Nation. The Congress concluded that losses and disruption caused by earthquakes could be substantially reduced through the development and implementation of earthquake hazards reduction measures."
