Etna's activity does not stop.
At 4:42 on March 12, the volcano began to "make itself felt" with a modest Strombolian-type activity in the South-East Crater at the same time as the intra-crater explosive activity in the localities of Voragine, Bocca Nuova and in the North Craters -East. In the meantime, there was an increase - with high values - of the typical volcanic tremor, located in the Southeast Crater at a depth of about 2.5 km asl
The volcanic phenomenon evolved at around 6:30 when an increase in the intensity and frequency of the Strombolian activity was recorded at the South East Crater.
This activity started to produce an eruptive cloud that reached a height of about 4000 m asl
Around 7:30 in the morning the Strombolian-type activity of the South East Crater further intensified causing, shortly after, a lava overflow towards the Valle del Bove, at an altitude of about 3000 meters above sea level and, subsequently, the usual phenomenology of lava fountains with the production of an eruptive cloud that rose up to about 6000 m in an easterly direction.
The lava flow, on the other hand, expanded towards the Valle del Bove reaching an altitude of about 2800 m asl
At about 8:40 the jets of the lava fountain of the Southeast Crater reached a height of about 500 meters from the crater. The lava flow produced by the overflow reached an altitude of approximately 1700 meters above sea level. At the peak of the activity, the eruptive column exceeded a height of 8500 m. The lava fountaining activity lasted until 10:50, passing to Strombolian explosions and ash emissions. At 11:15 the eruptive activity at the Southeast Crater ended while the eruptive activity of the other craters is continuing as in the previous weeks.
INGV constantly monitors the development of Etna's activity. As for past events, the usual laboratory analyzes on the composition of the volcanic glass of the erupted products are being carried out by the INGV-OE staff.
INGV promptly disseminates all information on Etna's paroxysms on the Institute's social channels. In particular, the INGVVulcani channels of Facebook, Twitter and Instagram are continuously updated also with the press releases constantly issued by the INGV Etna Observatory (INGV-OE) and with significant photos and images of the phenomena.
