Volcanic Ash Advisory Centers

Volcanic Ash Advisory Centers (VAACs) are organizations responsible for monitoring volcanic ash clouds and providing timely information to aviation and safety authorities. When a volcano erupts, ash can spread high into the atmosphere, posing risks to aircraft engines and navigation. VAACs track these ash clouds using satellite data, radar, and observations, then issue advisories on their location, size, and movement. This helps airlines and pilots make informed decisions to avoid dangerous ash, ensuring safety and minimizing travel disruptions. VAACs collaborate internationally to maintain global awareness of volcanic activity affecting air travel.
