Beginning January 01, 2026, the Kamchatka Volcanic Eruption Response Team (KVERT) of Institute of Volcanology and Seismology, Far Eastern Branch of the Russian Academy of Sciences (IVS FEB RAS) issues the Volcano Observatory Notices to Aviation (VONAs) that follow new standards set by the International Civil Aviation Organization (ICAO).

The new VONA format incorporates aviation-specific terminology, and, for the first time, a machine-readable version designed for seamless integration into aviation communication and flight-planning systems.

VONAs are issued to alert aviation professionals (aviation meteorologists, air traffic controllers, pilots, airline dispatchers, etc.) about volcanic activity that could affect flight safety. The update aligns VONAs with international recommended practices and ensures consistency with other aviation warning products distributed through the Aeronautical Fixed System of communication.

These changes apply only to VONA recipients.
KVERT will continue to provide information on volcanic activity to a wide audience in an accessible format:
– Volcano Activity Notices (VANs),
– Regular volcano status updates (Daily and Weekly).
