Volcanic Ash Advisory Centre

Volcanic Ash Advisory Centres (VAACs) are part of a global system to warn pilots about volcanic ash clouds. These clouds pose a significant danger to aircraft, as they can cause jet engines to fail and damage planes. The International Civil Aviation Organization manages a network of nine VAACs that monitor and report on volcanic ash. This information helps aviation authorities divert air traffic away from dangerous ash concentrations, preventing potential catastrophes. Volcanic ash itself can also cause secondary damage, such as roof collapses and crop failure, particularly in less developed regions. While ash falls can be destructive, volcanic activity also contributes to the formation of fertile soils over time.123
