Every year in the United States, natural hazards threaten lives and livelihoods and result in billions of dollars in damage. We work with many partners to monitor, assess, and conduct targeted research on a wide range of natural hazards so that policymakers and the public have the understanding they need to enhance preparedness, response, and resilience.

Hurricane Sandy Science

Hurricane Sandy Science

Hurricane Sandy made a variety of impacts along the highly populated northeastern Atlantic seaboard in October 2012. Improved understanding of these impacts will better prepare us for the next large storm.

Earthquakes are estimated to cost the nation $6.1 billion annually in building stock losses according to an updated report published today by FEMA.

Costs and consequences of natural hazards can be enormous; each year more people and infrastructure are at risk. We develop and apply hazards science to help protect U.S. safety, security, and economic well being. These scientific observations, analyses, and research are crucial for the Nation to become more resilient to natural hazards.
