Many techniques are available for reducing earthquake hazards; 36 are identified in this chapter. Six of these are described with examples redevelopment plans, regulatory zones, nonstructural building components, public information, unreinforced masonry buildings, and loss estimates. An overview of these techniques is useful to planners who implement hazard-reduction programs, to engineers who serve as advisors to local or state governments, and to decisionmakers who select the most appropriate technique for a given situation. Prerequisites for the successful use of these techniques are adequate and reliable scientific and engineering information, translation of such information for use by nontechnical users, and effective transfer of the translated information to those who will, or are required to, use it. List 1. EXAMPLES OF VARIOUS TECHNIQUES FOR REDUCING EARTHQUAKE HAZARDS Incorporating hazard information into studies and plans Community-facilities inventories and plans Economic-development analysis and plans Emergency and public-safety plans Land-use and transportation inventories and plans *Redevelopment plans (pre-event and post-disaster) Utility inventories and plans Regulating development *Creating special hazard-reduction zones and regulations Enacting building and grading ordinances Enacting subdivision ordinances Requiring engineering, geologic, and seismologic reports Requiring investigations in hazardous areas Reviewing annexation, project, and rezoning applications Siting, designing, and constructing safe structures Evaluating specific sites for hazards Reconstructing after a disaster *Securing nonstructural building components and contents Selecting the most resistant building system and configuration Siting and designing critical facilities Training design professionals and building inspectors Discouraging new development in hazardous areas Adopting utility and public-facility service-area policies Clarifying the liability of developers and government officials Creating financial incentives and disincentives " Informing and educating the public Posting public signs that warn of potential hazards Requiring nonsubsidized insurance related to level of hazard Strengthening, converting, or removing unsafe structures Condemning and demolishing unsafe structures Reducing land-use intensities or building occupancies Relocating community facilities and utilities Repairing unsafe dams or lowering their impoundments Retrofitting bridges and overpasses *Strengthening unreinforced masonry buildings Preparing for and responding to emergencies and disasters Conducting emergency or disaster training exercises ^Estimating casualties, damage, and interruptions Initiating community and corporate education programs Operating monitoring, warning, and evacuation systems Preparing emergency response and recovery plans Providing for damage inspection, repair, and recovery * Technique described and illustrated in this chapter. Prerequisite to the use of these reduction techniques are scientific and engineering studies. S...
