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
As Hurricane Sandy moved northward along the U.S. Atlantic coast in October 2012, USGS scientists worked to determine where and how the storm’s waves and surge might dramatically reshape the beaches and dunes that stand between the storm and coastal developments.
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.
An existing technological capability (not yet implemented in CA) for providing a few seconds of advance notification before arrival of earthquake-generated seismic waves causing ground shaking, with current efforts underway to move forward with providing users with the means to utilize the system for warning and preparedness action plans.
It aims at providing a unified system of space data acquisition and delivery to those affected by natural or manmade disasters through Authorized Users. Each member agency has committed resources to support the provisions of the Charter and thus is helping to mitigate the effects of disasters on human life and property.
Map interface to view and download LANDFIRE data sets, receive alerts and notifications.
Volcano-alert notifications are produced by Volcano Observatory scientists based on analysis of data from monitoring networks, direct observations, and satellite sensors. They are issued for both increasing and decreasing volcanic activity and include text about the nature of the unrest or eruption and about potential or current hazards and likely outcomes.
The Volcano Notification Service (VNS) is a free service that sends you notification emails about volcanic activity happening at U.S. monitored volcanoes. You can customize the VNS to deliver notifications for certain volcanoes or a range of volcanoes, and you can also choose the notification types you want to receive.
U.S. Geological survey scientists use fly-overs to track active lava flows.
Lava fountaining continues at fissure 8, although overnight crews reported reduced heights of 40-50 m (130-164 ft). The fountain has built a 35 m (115 ft) high cone, and an actively-growing spatter rampart on its eastern side. The ...
HVO scientists captured this aerial view of a much-changed Halema‘uma‘u during their overflight of the summit this afternoon. Explosions and collapse within Halema‘uma‘u have enlarged the crater (foreground) that previously hosted the summit ...
USGS Hawaiian Volcano Observatory Update of Kīlauea Volcano for June 4, 2018. On Camera: Jessica Ball, USGS Volcanologist.
This short video compilation shows conditions at Kapoho Bay during a helicopter overflight on June 4, 2018, around 6:15 a.m. HST and again around 1:38 p.m. HST. By 6:15 a.m., ...
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?
On October 12, USGS drones collected video footage of the Mud Creek landslide, which buried California State Highway 1 under a third-of-a-mile-wide mass of rock and dirt on May 20.
Coral reef expert Caroline Rogers was the only USGS employee in the Virgin Islands when the Category 5 storm hit.
In the past decade, the development of the Barnett, Eagle Ford, Marcellus, and other shales has dominated the national consciousness regarding natural gas. But in Alaska, another form of natural gas has been the focus of research for decades—methane hydrate.
An international team of scientists just finished probing the depths of the Pacific Ocean offshore of Alaska and British Columbia, to better understand the Queen Charlotte-Fairweather Fault. During the past century, the 700-mile-long fault has generated at least half a dozen major earthquakes, and future shocks threaten coastal communities in both the United States and Canada.
No, this EarthWord isn’t how natural gas quenches its thirst-it just sounds like it...
A study finds that although the “wilderness breach” created by Hurricane Sandy in 2012 has reached a relatively stable size and location, the channel and shoals will keep changing in response to weather. Related research shows the breach isn’t likely to increase storm-tide flooding in Great South Bay.
As thousands of people remain displaced by or are recovering from one of the four hurricanes that have affected the United States the past month, the U.S. Geological Survey is in the field providing science that will help with recovery from these historic hurricanes and with preparing for the next storm.
