Volcanic Ash Concentration

On Friday 14th December 2018, London VAAC will be occasionally issuing exercise Volcanic Ash products (including ash concentration charts). The products will appear on these and linked pages and will be clearly marked as TEST or EXERCISE. Please do not take any action on these products. In the event of a real eruption this message will be removed and all issued products will appear without the TEST or EXERCISE header.

Modelled Volcanic Ash Concentration forecasts are available from the links below.

Volcanic Ash Forecasts are only available from London VAAC for volcanoes erupting within the London VAAC area.

The VAAC are the Volcanic Ash Advisory Centres who hold the responsibility for advising on international aviation. For more information go to Volcanic Ash Advisory Centres
