After about 3 weeks of calm, activity at Etna volcano, Italy intensified again around 15:00 UTC on August 29 with a transition to lava fountaining at 16:45 UTC, marking the volcano's 50th paroxysmal eruptive episode since February 16, 2021. The strong explosive activity lasted to 18:00 UTC.

The Aviation Color Code was raised to Red at 15:25 and lowered back to Orange at 04:15 UTC on August 30.

Dark ash plumes from the crater rose to an estimated 9 km (30 000 feet) above sea level at 17:10 UTC and drifted eastward.

At 03:45 UTC on August 30, SO2 cloud was clearly identifiable from satellite data over Greece, drifting eastward and dissipating.
