Volcanic Ash Advisory Centers (VAAC)
Volcanic Ash Advisory Centers (VAACs) are specialized organizations that monitor and provide information about volcanic ash clouds that can affect aviation and air travel. They track ash plumes from eruptions using satellite data, ground reports, and aircraft observations, then analyze their size, height, and movement. VAACs issue regular advisories to airlines, airports, and relevant authorities to ensure safety, helping prevent ash encounters that can damage aircraft engines or impair visibility. They coordinate internationally to provide timely, accurate updates, playing a critical role in managing the risks associated with volcanic eruptions in the aviation industry.
