Explosive activity accompanied by abundant ash emission resumed at Etna volcano at 11:15 UTC on December 14, 2021. Ash is dispersing south of the crater.
Today's activity comes just a day after a small lava flow appeared at a new vent on Etna's eastern flank. The flow settled at an estimated altitude between 1 700 - 1 800 m (5 600 - 5 900 feet) a.s.l.1
This activity was accompanied by a gradual increase in the average amplitude of volcanic tremor to high values.
Explosive activity at the volcano resumed at 11:15 UTC on December 14.
The Aviation Color Code was raised from Orange to Red at 11:54 UTC after very strong ash emission to 5.5 km (18 000 feet) a.s.l.
Mount Etna, towering above Catania, Sicily's second-largest city, has one of the world's longest documented records of historical volcanism, dating back to 1500 BCE.
Historical lava flows of basaltic composition cover much of the surface of this massive volcano, whose edifice is the highest and most voluminous in Italy
