Increased explosive activity accompanied by significant ash emissions started at Etna's New Southeast Crater (NSEC) shortly before 06:00 UTC on Friday, October 23, 2020. The Aviation Color Code was raised to Red at 05:53 UTC and lowered back to Orange at 08:36 UTC.
According to the Toulouse VAAC, volcanic ash rose to 2.4 km (8 000 feet) above sea level, drifting SE.
The Catania airport management said its 'Crisis Unit ordered the closure of a sector of the airspace starting at 09:30 LT.'
The unit allowed 5 landings per hour but did not limit departures, although cautioned delays might occur.
Flights returned to normal at 10:54 UTC.
Strombolian activity of varying intensity, sporadic and mild ash emissions continued at the NSEC and Bocca Nuova.
