NASA recently released the Earth Observatory Natural Event Tracker (EONET), an API that provides a curated collection of natural events as well as a way to link those events to image layers. EONET is expected to enable developers to build their own client applications on top of NASA data.
NASA introduced the API because the public can currently browse the entire globe using specialized client applications (e.g., NASA WorldView, Google Earth, etc.) to look for natural events as they occur, but the user's experience is guided, and therefore restricted, by the client application.
EONET metadata is for visualization and general information purposes only and should not be construed as official with regards to spatial or temporal extent.
