Code orange for Kambalny volcanic eruption in Russia
by Hugues Brenot (BIRA-IASB) 18 April 2017
On 24 March 2017, the Kambalny strato-volcano, located in Southern Kamchatka peninsula, in the east of Russia, started to erupt. Orange warning has been attributed by the Russian specialists, indicating threatening dangers for aviation. It means that this volcanic plume can contain ash and SO2 with high concentration and reach a height of 6 to 8 km (threatening international flights or low-flying aircraft). According to the KVERT of the Institute of volcanology and seismology Olga Girina, the last eruption of this volcano happened more than 200 years ago.
The Support to Aviation Control System is part of the Early Warning System developed by EUNADICS-AV project. Notifications sent to Users (like the VAACs of Anchorage and Tokyo) and near-real time monitoring of the volcanic plume of Kambalny (moving over the Pacific Ocean, southeast of Kamchatka) has been achieved, starting on the early morning of the 25th of March 2017 (few hours after the start of this eruption).
Note that in the same time, Kliuchevskoi volcano, located about 600 km north of Kambalny, is also erupting (as observed by OMI SO2 images on 25 and 27 March 2017).
