All Data
Explore all data by the topics and refine type to find the digital information in a format suitable for direct input to software that can analyze its meaning in the scientific, engineering, or business context for which the data were collected.
Subscribe to Volcano Notification Services
The Volcano Notification Service (VNS) is a free service that sends you notification emails about volcanic activity happening at U.S. monitored volcanoes. You can customize the VNS to deliver notifications for certain volcanoes or a range of volcanoes, and you can also choose the notification types you want to receive. Notifications are issued by the five U.S. Volcano Observatories.
Programmatic Access
A well-structured format readily parsed by most programming languages. This is a good option for software developers wishing to use earthquake data.
QuakeML
A flexible, extensible and modular XML representation of seismological data which is intended to cover a broad range of fields of application in modern seismology.
Spreadsheet Applications
A simple text format suitable for loading data into spreadsheet applications. This is a good option for manual scientific analysis.
Atom Syndication
A basic syndication format supported by a variety of feed readers. This is a good option for casually subscribing to earthquake information.
Earthquake Notification Service
The Earthquake Notification Service (ENS) is a free service that sends you automated notifications to your email or cell phone when earthquakes happen.
Landslide Monitoring
Monitoring is essential to predicting the behavior of landslides and forecasting which storms can trigger landslides. Graphs showing the most recent data are updated regularly with update cycles ranging from 15 minutes to 24 hours. Landslide monitoring data and information provided on this web site are preliminary and have not been reviewed for accuracy; therefore the data are subject to revision.
Real-Time HEZF Display
Real-time HEZF index display from USGS geomagnetic observatories internet feeds without filling gaps with satellite data
Surface-water data for Wisconsin
Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Wisconsin. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
Groundwater data for Wisconsin
Data from wells, springs, test holes, tunnels, drains, and excavations in Wisconsin; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.
