#Volcano Activity Notice

The Volcano Observatory Notice to Aviation is a notification product used by volcano observatories globally to inform the aviation community (pilots, air traffic managers, dispatchers, meteorologists, and airlines) of volcanic activity that could pose a hazard to aviation. An upcoming change in message formatting will improve the way that the aviation community gets this information.

Record-setting lava fountain and plume heights were reached during Episode 23 of the Kīlauea summit caldera eruption. Given increasing airborne hazards associated with each new eruptive episode, Hawaiian Volcano Observatory is changing its episode notification types.
