This application allows the display and query of drought probability. Maximum likelihood logistic regression is used to estimate drought probabilities for selected Northeast region streams.

This story map provides an overview of the 3D Elevation Program (3DEP) and highlights how lidar data support hazards applications for volcanoes, earthquakes, landslides, hurricanes, flooding, drought and wildfires. An assessment of 3DEP data coverage as of June 2020 for high-risk areas of landslides, fires and hurricanes is presented.

Hurricane Maria made landfall in Puerto Rico on September 20, 2017, bringing with it a mix of high winds and extreme rainfall. This data visualization animates Hurricane Maria's Water Footprint, the cumulative precipitation the storm dropped on the island, and the impact of rainfall on river gage height.

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 Hurricane Irma Water Footprint data visualization animates the hurricane's path, cumulative precipitation, and its impact on river gage height.

Hurricane Harvey approached the U.S. Gulf coast on August 25, 2017. The Hurricane Harvey Water Footprint data visualization shows the hurricane's impact on precipitation and streamflow.

Hurricane Matthew approached the southeastern U.S. coast on October 7, 2016. This is a data visualization that shows the hurricane's impact on precipitation and streamflow.

Microplastics, plastic particles less than 5 millimeters in diameter, are a contaminant of emerging concern in aquatic environments. This interactive visualization explores classifications and potential sources of microplastics in the Great Lakes.

Since 2000, the Colorado River Basin has been experiencing a historic, extended drought that has impacted regional water supply and other resources, such as hydropower, recreation, and ecologic services. This visualization is part of a multi-agency effort to showcase the usefulness of open data by exploring the current 16-year drought and its effects on the Colorado River Basin.

In 2017, the State of California was experiencing one of the most severe droughts on record, which has implications for citizens of California and beyond. This website graphically visualizes these data to help understand the effect of drought on rivers, streams, lakes, and reservoirs.

A geonarrative (Esri Story Map) describing what it might be like the next time the Hayward fault has a large earthquake. Scientists examined a hypothetical earthquake, the magnitude 7.0 HayWired earthquake scenario.

In 2016, the National Geological and Geophysical Data Preservation Program (NGGDPP) sponsored data and collection preservation projects conducted by state geological surveys. Descriptions of state preservation projects, including access to preserved collections via state geological survey websites and the NGGDPP National Digital Catalog, are provided.

The degree to which eelgrass on river deltas provides critical habitat for estuarine fishes, especially out‐migrating juvenile salmon, is an important scientific and management issue that bears on efforts to conserve and restore both eelgrass and fish.
