The monitoring stations of the Etna Observatory of the National Institute of Geophysics and Volcanology (INGV-OE) recorded, starting at 21:00 local time on 29 May 2019, an increase in the amplitude of the volcanic tremor which reached its maximum maximum at 03:50 on 30 May. This phenomenology preceded the opening, at an altitude of about 3.150 m asl, of an eruptive fissure at the northern base of the New South East Crater. From this fissure, starting at 03:20, a lava flow is emitted which is developing along the western wall of the Valle del Bove. The most advanced lava front of this flow at 10:15 was around 2.050 m of altitude.
Starting at 05.35, the network of surveillance cameras showed the opening of another eruptive fissure located at the south-eastern base of the New South East Crater at an altitude of about 3.050-3.000 m asl
This fissure is affected by a weak explosive activity and by the emission of a lava flow that is expanding along the western wall of the Valle del Bove in the direction of Serra Giannicola Grande, partially overlapping on the lava flow of 24-27 December 2018. The more advanced lava front at 10:15 was at an altitude of about 2.260 m asl
During this eruptive phase the New South East Crater is producing a volcanic cloud with ash fallout on the North East side of Etna.
An inspection by INGV-OE personnel is currently underway in the summit area.
The Etna Observatory and the Palermo Section continue to monitor the volcano continuously.
