June 6, 2017

USGS collects groundwater data at varying measurement frequencies to monitor the hydrologic conditions on Long Island, New York. Each year during April and May, the USGS conducts a synoptic survey of water levels to define the spatial distribution of the water table and potentiometric surfaces within the three main water-bearing units underlying Long Island.

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.
