The aviation community, under the direction of the International Civil Aviation Organization (ICAO), came together across multiple time zones on 15 and 16 January 2013 for an international exercise called VOLKAM13 on volcanic eruption in the Far East of the Russian Federation.
The objective of the exercise was to test the flow of information about volcanic ash that is produced by the Kamchatka Volcanic Eruption Response Team in Petropavlovsk-Kamchatsky in the Russian Federation (KVERT), the Volcanic Ash Advisory Center (VAAC) in Tokyo, the Meteorological Watch Offices and the International NOTAM (Notice to Airmen) Offices.
During the exercise the explosive eruption of Karymsky volcano, located on Kamchatka peninsula, emitted volcanic ash to a height of about 12.5 km (FL410). The ash shifted to the southeast direction with a speed of 110 km per hour and caused pollution of the air space used for international airways (G583, B244, B932, G73). As part of the exercise, NOPAC (Northern Pacific) tracks were modeled. >> full text
