Here we try to answer some of your questions on volcanic ash prediction, roles and responsibilities and provide links to other relevant organisations.
The answers to the below can be revealed by clicking on the questions.
The Met Office is one of nine International Civil Aviation Organisation (ICAO) recognised Volcanic Ash Advisory Centre (VAAC). We are responsible for giving advice to European Met Watch Offices on the dispersion of ash clouds emitted from volcanoes in the North East Atlantic; primarily from Iceland. Met Office volcanic ash forecasting developments. We run our model to advise were the ash is likely to be. Find out more about volcanic ash modelling by the Met Office on YouTube.
That is for the aircraft manufacturers and the airlines to determine.
For up-to-date details on airspace restrictions please check the NATS website or contact your tour operator or airline for details on flight plans.
Met Office modelling can give you good advice about where the ash is likely to be. It could also be visible in the sky as a grey/brown cloud or seen as a thin grey film on objects like cars.
Although it is too early to say what impact the eruption may or may not have, the scale of the plume is currently not sufficiently large enough to have a major affect on global weather or climate. When compared to previous volcanic eruptions which have had an impact on the climate, this one is less powerful.
