Alle ore 11.17 locali la Sala Operativa dell’Osservatorio Etneo dell’INGV ha diramato il comunicato VONA (Volcano Observatory Notice for Aviation) di livello ROSSO per emissione di cenere vulcanica dall’Etna.
Nuvole di cenere sono state osservate senza cambiamenti significativi dal suolo a FL180 a nord-est. Alle 14.20 locali sono state attivate le procedure di contingecy: chiusi a tutto il traffico GAT i settori A3 di Reggio Calabria e Catania, ovvero tra 030° a 077° dal vulcano.
Con nube nel settore A3 le STAR NATOV 1F/1G/1M/1L, PIMOR 1F/1G/1M/1L/1P/1S/1R, DIVAR 1F/1G/1F e le SID RCA 6A/6B, PIMOR 6A/6B/6F, PEKOD 5A/5B di Catania sono sospese. A Reggio Calabria sono sospese le SID CDC 6A, PIGER 7D, BERMI 5A, INDAX 5B, BERMI 5B, CDC 6B, PIGER 7C, le STAR BERMI 1A/1B e le procedure di avvicinamento LOC D/E/F.
