Etna is tonight still at it and the current eruption has now been officially declared the most energetic of the last 20 years by Italy's National Institute for Geophysics and Volcanology.
This morning Fontanarossa [Catania] airport closed for an hour because the runway was covered in ash and closed again this evening. It will remain closed until at least 6 am tomorrow, when a crisis meeting on the situation will be held. Today some flights due to land at Catania were diverted to Comiso and Palermo.
It is reported that this morning the column of magma, ash and gas erupting from the central crater at one point reached a height of seven kilometres. The small towns around Etna are also said to be covered in ash.
