The main purpose of this legislation is to renew and enhance the Earthquake Hazards Reduction Act of 1977. The goal is to improve the nation's ability to prepare for, respond to, and recover from earthquakes, thereby reducing the risks and impacts associated with such natural disasters. Key provisions of the legislation include several updates and expansions to existing programs. It broadens the scope of earthquake hazard reduction activities to include not just local and state governments, but also Tribal governments.
