Geologic Map of Alaska
This is an interactive version of the Alaska geologic map database which allows a user to view and access many features of the database and map through a standard web browser. In other words, there is no need for or knowledge of specialized GIS software.
Oahu Tsunami Evacuation Dashboard
Tsunami waves created by earthquakes far from Hawai’i arrive hours later along Hawaiian shorelines but can be difficult to escape if everyone uses their cars to evacuate. Working with the Hawai’i Emergency Management Agency, researchers with the U.S. Geological Survey (USGS) used computer modeling to identify areas where people should be able to evacuate on foot in less than 15 minutes.
Nowcast Beach Status
NowCast – A daily nowcast of recreational water quality conditions
Nowcast predicts water quality conditions at select beach swimming areas in Lake Erie and Lake Ontario. Predictions are only posted during the beach swimming season in Ohio, Pennsylvania, and New York.
Earthquake-Triggered Ground-Failure Inventories
Earthquake-triggered ground-failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake hazard analyses is limited.
Coastal Change Hazards Portal
Interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Displays probabilities of coastal erosion.
San Diego Hydrogeology Data Map
Map of the San Diego Hydrogeology project study area with links to groundwater and surface water data for each of the monitoring sties.
Recent earthquakes in Oklahoma
Information on the latest earthquakes in Oklahoma.
GloVis
The USGS Global Visualization Viewer (GloVis) is an online search and order tool for selected remote sensing data.
MODFLOW
MODFLOW is the USGS's three-dimensional (3D) finite-difference groundwater model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions.
SPARROW
SPARROW (SPAtially-Referenced Regression On Watershed attributes), is watershed based and designed for use in predicting long-term average values of water characteristics, such as concentrations and amounts of selected constituents that are delivered to downstream receiving waters.
