Volcanic Ash Monitoring and Forecasting at the London VAAC

A volcanic eruption occurs about once every four or five years in Iceland. The London Volcanic Ash Advisory Centre (VAAC) monitors, and forecasts, the volcanic ash movement over Iceland, the United Kingdom, and the north-eastern part of the North Atlantic Ocean. This covers some of the busiest airways in the world, even though it is a relatively small area. Strong winds often spread ash downward from a volcano, so a volcanic eruption on Iceland can quickly impact a large area of airspace. During the eruption of a volcano on Iceland, the London VAAC interacts closely with forecasters at the Icelandic Meteorological Office. The London VAAC has complete access to the latest observations as they emerge.
