September 22, 2017

Hurricane Maria made landfall in Puerto Rico on September 20, 2017, bringing with it a mix of high winds and extreme rainfall. Much of the island experienced flooding and structural damage along with a loss of electricity and water.

Locations of observed coastal change due to Hurricane Harvey
September 21, 2017

Following Hurricane Sandy, the US Geological Survey (USGS) received $18.8 million in supplemental funding to better understand coastal flooding, to improve our preparedness for future coastal storms, and to increase the resilience of coastal cities, infrastructure and natural systems.

September 14, 2017

Hurricane Irma, the most intense hurricane observed in the Atlantic in the last decade, approached the west coast of Florida on September 10th, 2017. This animation shows the precipitation and river conditions through time as Irma moved over the southeastern United States.

The USGS Flood Inundation Mapping Program (FIM) partners with local communities and other government agencies to develop and validate flood inundation map libraries. Click the title above to visit the USGS FIM website and learn more about available tools. Completed projects are collected on the USGS National Flood Inundation Mapper, brought to you by the USGS Wisconsin Internet Mapping Group (WiM)

Drought probabilities (%) from February (2002) mean discharge
July 18, 2017

Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams. Hydrologic drought streamflow probabilities for summer months are provided as functions of streamflows during the previous winter months. This application allows the display and query of these drought streamflow probabilities for Virginia streams.

April 12, 2017

The Hazard Exposure Reporting and Analytics (HERA) application was developed to provide users with insight on potential population, economic, land cover, and infrastructure vulnerability resulting from a given hazard. Interactive maps and graphics allow users to examine hazard exposure for individual communities, to compare exposure for multiple communities and changes in hazard exposure.

Hurricane Louisiana Coast
September 14, 2016

June 1 marks the beginning of hurricane season. Should storms arrive on the Louisiana coast, the people in coastal communities across the State, along with many Federal, State, and local agencies will need to know how the storms are affecting the coastal and low-lying areas.The USGS maintains an extensive network of coastal gages that provides critical time-sensitive water level.

May 19, 2016

The USGS partners with the Association of American State Geologists (AASG) to develop a distributed archive of standardized geoscience information for the nation.

Fish on seafloor, Offshore Northern California
April 14, 2016

CSMP is a cooperative program to create a comprehensive coastal and marine geologic and habitat base map series for all of California's State waters. Data collected during this project reveal the seafloor offshore of the California coast in unprecedented detail and provide an ecosystem context for the effective management of this precious marine resource.
