Explosive activity accompanied by heavy ash emission resumed at Etna volcano at 11:15 UTC on December 14, 2021. Ashes are dispersing south of the crater.
Today’s activity came just one day after a small lava flow appeared in a new vent on Etna’s eastern flank. The flow stopped at about 1,700 to 1,800 meters (5,600 to 5,900 feet) above sea level.
This activity was accompanied by a gradual increase in the average amplitude of the volcanic tremor to high values.
Explosive activity on 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 a very strong ash eruption up to 5.5 km (18,000 ft) above sea level.
“The phenomenon has been observed by visible and thermal cameras since 11:15 UTC,” the Etna Volcano Observatory reported.
