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
Explore critical pre- and post-disaster images and datasets online for immediate viewing and downloading. These images are used in disaster preparations, rescue and relief operations, damage assessments, and reconstruction efforts. We supply satellite and aerial images for analysis of disaster areas before, during, and after a disaster.
Research projects within the USGS Geomagnetism Program are targeted for societal relevance, especially for space-weather hazard science.
The IGEMS provides the public with both an overview and more specific information on current natural hazard events. The Department of the Interior’s Office of Emergency Management provides it as an internet-accessible service.
The USGS Geomagnetism Program currently operates 14 magnetic observatories. Magnetometer data are collected at these facilities, and the data are then transmitted to Program headquarters in Golden, Colorado.
The AVO is a partnership among the USGS, the Geophysical Institute of the University of Alaska Fairbanks, and the Alaska Division of Geological and Geophysical Surveys. To mitigate volcanic hazards, AVO monitors and studies Alaska's hazardous volcanoes to forecast and record eruptive activity. AVO also monitors volcanic activity in the Commonwealth of the Northern Mariana Islands.
Our Program researches activities to make accurate landslide hazard maps and forecasts of landslide occurrences.
CalVO operates real-time volcano monitoring networks, disseminates forecasts and notifications of significant activity, assesses volcano hazards, researches volcano processes, and works with communities to prepare for volcanic eruptions in California and Nevada. The Observatory is located at USGS offices in Menlo Park, California.
Landslide sites and data for learning more about the physical processes that trigger landslides or control their movement.
The CVO staff conduct research on many aspects of active volcanism, respond to dangerous volcanic activity in many parts of the world, and maintain a close watch over volcanoes in Washington, Oregon and Idaho. The USGS established CVO in Vancouver, Washington, after the May 18, 1980, eruption of Mount St. Helens.
Tsunami awareness public service announcements come from collaboration among the USGS SAFRR team, outside partners, and Pasadena's Art Center College of Design.
HVO operates monitoring networks, assesses hazards, and issues notifications of volcanic activity and earthquakes in the State of Hawai‘i. HVO scientists conduct fundamental research on volcanic processes and work to educate the communities at risk. HVO is located in Hawaiʻi Volcanoes National Park on the Island of Hawaii.
The Estuarine Physical Response to Storms Project will assess the estuarine and adjacent wetland responses of three Atlantic lagoonal estuaries to major storm events such as Hurricane Sandy. The estuarine systems include the Barnegat Bay-Little Egg Harbor Estuary, the Chincoteague Bay, and Jamaica Bay, NY. Evaluations of sediment transport, geomorphic change, circulation, wetland stability....

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.
When a major storm is on the horizon, the USGS uses its water monitoring, coastal change, mapping, and modeling expertise to help prepare for, respond to, and recover from hurricanes and tropical storms.
Editor’s note: this news release will be updated online with more information on the streamgage records being set in Texas as it becomes available.
Rivers and streams reached record levels as a result of Hurricane Harvey’s rainfall, with about 40 U.S. Geological Survey streamgages measuring record peaks.
As Harvey’s record breaking rainfall and catastrophic flood waters recede in Texas and western Louisiana, U.S. Geological Survey teams are collecting high water marks, monitoring water levels and coastal change, retrieving storm tide sensors and collecting samples for water quality analysis.
A magnitude 8.1earthquake struck offshore Chiapas, Mexico on September 7, 2017 at 11:49 local time (September 8 at 04:49UTC).
With hurricanes in the east and wildfires in the west, natural hazards have the potential to impact a majority of Americans every year. USGS science provides part of the foundation for emergency preparedness whenever and wherever disaster strikes.
To learn more about USGS’ role providing science to decision makers before, during and after Hurricane Harvey, visit the USGS Hurricane Harvey page.
Reporters: Do you want to interview USGS scientists as they measure flooding? Please contact Jennifer LaVista or Lynne Fahlquist.
U.S. Geological Survey field crews are measuring record flooding in parts of south-central Texas following intense rainfall from Tropical Storm Harvey.
