eonet

EONET, the Earth Observatory Natural Event Tracker, is a public catalog and API maintained by NASA’s Earth Observatory program. It aggregates information about natural events around the world and provides access to event records for researchers, developers, and the public. The catalog covers a wide range of event types, including earthquakes, wildfires, storms, floods, volcanoes, landslides, droughts, and other observable phenomena detected by satellite imagery or ground-based sources.

Each event in EONET includes an identifier, a title, a description, one or more categories, a date or time range, location data as geometry (points or polygons), and references to data sources and links for further information. The data model supports multiple categories per event and geographic footprints that facilitate mapping and spatial analysis.

Access to EONET is provided through a RESTful API, with endpoints to list and search events, categories, and geographic regions. The API supports queries by date range, category, bounding box, and other parameters, making it suitable for integration into dashboards, research workflows, or disaster response tools. The API version commonly used is v2.x, accessible at the EONET domain, and the service also offers a category and region browser.

Data in EONET are sourced from NASA’s Earth Observatory and partner providers, and are intended to be openly accessible for non-commercial and educational use. The catalog is periodically updated to reflect new observations and reports, providing a centralized, up-to-date resource for monitoring natural events worldwide.
