Volcanic Ash Advisory Center (VAAC)

A Volcanic Ash Advisory Center (VAAC) is a specialized organization that monitors and reports on ash clouds produced by volcanic eruptions. Using satellite data, aircraft observations, and ground reports, VAACs track the size, location, and movement of ash clouds that can affect aviation, air travel, and safety. They issue regular advisories to airlines, pilots, and authorities to help avoid hazards caused by volcanic ash in the atmosphere, ensuring safer skies and minimizing disruptions during volcanic events.
