Etna (Sicily, Italy): (17 Feb) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 12000 ft (3700 m) altitude or flight level 120 and is moving at 10 kts in S direction.
The full report is as follows: ERUPTION AT 20210216/1610Z SPORADIC ASH EMISSION STILL OCCURS to 12000 ft (3700 m)
...16 Feb:
This afternoon, Etna produced a very spectacular lava-fountaining eruptive episode, known as paroxysm.
Starting from around 5 p.m. local time in the afternoon, the strombolian activity, which had been going on for the past weeks from the New SE crater intensified significantly. Shortly after, a lava overflow was observed from the eastern side of the South East crater. At 16:05 UTC (5:05 p.m. local time), a part of the eastern flank of the cone collapsed into a pyroclastic flow that traveled down the western wall of the Valle del Bove depression.

The flow, as hot material was sliding over snow, produced an ash and steam cloud that quickly dispersed from high altitude winds to the south.
5 minutes later, the explosive activity at the SE crater increased further into lava fountains several hundred meters high, which produced a tall ash plume that rose to up to approx. 10 km elevation (30,000 ft) above sea level, i.e. 7 km above the craters.

The explosions generate glowing lava bombs ejected to an approximate height of 200 to 250 meters above the crater.
The lava flow on the S-SW flank remains active, currently about 650 m long and caused glowing and hot avalanches of material.
