Etna entered August 2021 with continued growth at its Southeast Crater and impressive paroxysmal eruptive episode, the first since July 20.
Strombolian activity at the crater gradually intensified into lava fountaining by 21:22 UTC on July 31. The episode lasted through 23:30 UTC, with lava fountains reaching a height of about 1 km (3 300 feet) a.s.l.
A SW lava flow produced during the event reached an altitude of 2.8 km (9 200 feet) a.s.l. at 21:43 UTC.
The Aviation Color Code was raised to Red at 18:23 UTC and lowered back to Orange at 05:47 UTC on August 1.
