This site is designed to provide information on federal interagency and cooperative developments related to coastal sand and gravel resources and management issues along the Atlantic continental margin.
A geologic and oceanographic study of the waters and Continental Shelf of Gulf of the Farallones adjacent to the San Francisco Bay region. The results of the study provide a scientific basis to evaluate and monitor human impact on the marine environment.
This web site is an outgrowth of an agreement between the USGS and the New England Aquarium, designed to summarize and make available results of scientific research. It will also present educational material of interest to wide audiences.
USGS responses to and studies of the hazards and impact of major hurricanes, tsunamis, and El Nino storms. Includes links to oblique aerial photography and LIDAR surveys recording coastal changes and other effects of storms and waves.
Sedimentary characteristics of 228 tsunami deposits, drawn from published accounts, for interpreting prehistorical, historical, and modern tsunami deposits, and for the development of criteria to identify tsunami deposits in the geologic record.
Online catalog of scientific reports and data around and about Monterey Bay, California, indexed by author, agency, project, location, feature type, and topic
Article in the May 28, 1998 issue of Volcano Watch describing of correlation of earth tides to volcanic eruptions and value in monitoring underground magma movement with deformation measurement instruments including tiltmeters and strainmeters.
Fact sheet on hazards from earthquakes and tsunamis in Puerto Rico and the U.S. Virgin Islands to be downloaded as a PDF file or viewed as an Adobe Acrobat Reader file.
By measuring the current and historical growth rates of coral skeletons, and using field experiments, we intend to find out whether rising atmospheric CO2 and rising sea levels will cause coral reefs to erode and cease to function.
Homepage for programs of the Center for Coastal Geology on hurricanes and extreme storms with links to technology, related aerial photography, hurricanes, El Nino, northeasters, and specific storms.
Characteristics of recent tsunami deposits, with the knowledge we have about the events that caused them, give us ways to recognize ancient deposits of this type and infer characteristics of those ancient tsunamis as well.
Guidelines for correct tsunami response and community preparedness from local emergency managers, first-responders, and leading experts on tsunami hazards and warnings.
The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat.
Describes the role USGS plays in reducing losses from natural disasters, itemizing specific information we develop and maintain to help mitigate or avoid these problems.
News and related information about the importance of seven major types of natural hazards in the United States: earthquakes, floods, wildfires, hurricanes, landslides, volcanoes, and tsunamis.
Research and monitoring to provide the Nation with a clear understanding of natural hazards and their potential threats to society, and assists with developing smart, cost-effective strategies for achieving preparedness and resilience.
A network of tide gages and weather stations is deployed in coastal areas across the state to help forecast floods and support timely evacuation of people from affected areas.
With high property damage, loss of life and fire damage were relatively low. Why? The legal system encourages builders to follow code, the electrical grid was shut down early, and emergency response management was very effective.
