The Istituto Nazionale di Geofisica e Vulcanologia (INGV) reported that a new eruptive fissure opened at the volcano yesterday.

The new fissure vent is located on the northeastern flank of the SE crater at an altitude of approx. 2800 meters. The vent has been producing a small lava flow descending down the Valle del Leone valley.
Etna itself is currently snow-covered and contact with the lava flow may likely cause an explosion of steam and water, i.e., steam driven only, caused by overheated water flashing to steam.
Prior to the eruption, a typical rise of volcanic tremor to high values has been detected, indicating moving magma upwards through the volcanic conduits. Consequently, it decreased again to medium levels and it still continues like that at the time of this update.

During the past weeks and months, the volcano has remained relatively calm. Most monitored parameters (seismic, degassing, ground deformation etc activity) have not shown significant variations and are generally around low to moderate levels, typical for most intervals between eruptive episodes. ...

Etna volcano (Sicily, Italy) - Smithsonian / USGS Weekly Volcanic Activity Report for 15 June-21 June 2022 (Continuing Activity)
INGV reported that during 13-19 June gas emissions rose from Etna's Southeast Crater (SEC) and Bocca Nuova Crater (BN); the emissions from BN were dense and voluminous on 13 June and drifted SSW. Lava effusion from the vent located at about 2,700 m elevation, along the fissure that had opened on 29 May, had slowed by 13 June and stopped by that evening. Lava continued to erupt from a vent along the 7 June fissure, located at the base of the N wall of the Valle del Bove, advancing to 1,760 m elevation by 14 June. ... Read all
