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.Read Our Science Strategy
SAFRR brings together tsunami and communication experts to discuss potential changes to safety messages, based on improved scientific understanding of Hawaii's tsunami hazard.
Students at Art Center College of Design learned about tsunamis from SAFRR partners in natural science, social science, and emergency management, then designed a fun, engaging, multi-faceted awareness campaign.
Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.
We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.
Our scientists conduct research studies focused on geologic mapping, sampling and understanding of mineral and energy resources and studies of the geologic setting and processes to inform renewable energy development offshore.
We bring together multidisciplinary expertise focused on developing tools and models to improve understanding of how healthy ecosystems function as well as how they respond to environmental changes and human impacts including ecosystem restoration. Research studies address coral reef, coastal wetland, benthic habitat and groundwater resources.
USGS scientists at the Wetland and Aquatic Research Center and other offices received funding for studies related to habitat change, storm surge and ecological modeling, migratory bird impacts, and other topics of interest. The Hurricane Sandy Spatial Data Mapping Application showcases the data and analytical products resulting from these studies.
The Volcano Hazards Program develops long-range volcano hazards assessments. These includes a summary of the specific hazards, their impact areas, and a map showing ground-hazard zones. The assessments are also critical for planning long-term land-use and effective emergency-response measures, especially when a volcano begins to show signs of unrest.
The HayWired project is an earthquake scenario currently underway to model and study impacts on the San Francisco Bay area from a Mw 7.05 earthquake on the Hayward fault.

Documentary features USGS researchers
The USGS has up-to-date details on the November 12, 2017 event.
Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?
