Volcanic Ash Advisory Center

from Wikipedia, the free encyclopedia
Monitored areas

Volcanic Ash Advisory Centers (VAAC) are nine warning centers commissioned by the International Civil Aviation Organization (ICAO) as part of the International Airways Volcano Watch (IAVW). These are operated by meteorological organizations designated by the ICAO . They were set up from 1993 to observe the occurrence of volcanic ash in the air and to warn air traffic of dangerous ash clouds. Among other things, volcanic ash can cause jet engine failure and thus seriously endanger aircraft.

Locations

The areas of responsibility of the individual VAACs cover most of the world, with the exception of part of northern Russia and the Arctic, part of the southern Pacific Ocean and Antarctica. The boundaries of the respective areas of responsibility are determined by coordinates or coincide with the corresponding flight information area (FIR).
