Explore Current Natural Hazards with the new NASA Worldview/EONET Events Feature
Imagery and information about current natural hazard events are only a click away thanks to a collaboration between Worldview and the Earth Observatory Natural Event Tracker (EONET).

Users of NASA’s Worldview (https://worldview.earthdata.nasa.gov) application may have noticed a new “Events” tab sandwiched between the “Layers” and “Data” tabs in the upper left home page window. Clicking on the Events tab reveals a list of natural events, including wildfires, tropical storms, and volcanic eruptions. Selecting one of these events transports users seamlessly back in time to imagery and data about the selected event. Almost 50 events currently are part of the Worldview Events feature.
Viewing an event is simple. Click on the Worldview Events tab in the upper left corner of the Worldview home page to bring up a chronological list of events. Once an event is selected, Worldview zooms to the location and date of the event. In the animation below, California's Gap Fire from August 27 is first selected. Immediately, Worldview zooms to the Terra/MODIS (true color) image of Northern California for August 27, which also includes the Fire and Thermal Anomalies (day and night) Terra/MODIS layer with red dots indicating the fire's detected hot spots. Next, Hurricane Hermine is selected, which brings up four separate images showing the progression of this recent storm. Additional data layers can be added to a selected event’s imagery with a few mouse clicks through the existing Worldview functionality.
In addition, each event has a link to information about the event. For example, clicking on the Events tab for the Gap Fire near the California/Oregon border provides a link to the Incident Information System web page about this fire.
The Events feature is a collaboration between Worldview and NASA’s Earth Observatory Natural Event Tracker (EONET). EONET is an application program interface (API) that provides a continually curated list of natural events. In addition, each event has links to related near real-time image layers for viewing in client applications such as Worldview.
Worldview is a natural partner with EONET since it already provides access to hundreds of imagery layers created from data collected by instruments aboard Earth observing satellites. Many of these images are available within three to four hours of a satellite overpass, making these near real-time images an invaluable tool for managers, forecasters, and researchers needing a quick view of an event without the need for the more heavily processed data required for scientific research.

NASA’s fleet of Earth observing satellites collect data about our planet 24/7. Images produced from these data become part of NASA’s Global Imagery Browse Services (GIBS). GIBS is part of NASA’s Earth Observing System Data and Information System (EOSDIS), and provides access to over 240 trillion pixels’ worth of imagery designed to provide a quick overview of an event or a summary of atmospheric data for rapid analysis. GIBS images can be browsed interactively through clients such as Worldview, which also allows users to download the underlying data.
NASA’s EOSDIS provides end-to-end capabilities for managing NASA’s Earth science data. The primary services provided by EOSDIS are data archive, management, and distribution; information management; product generation; and user support services. These services are managed by NASA’s Earth Science Data and Information System (ESDIS) Project.
