The current series of paroxysmal eruptive episodes at Etna proceed at a rather frantic pace, with intervals of just over a day between eruptive crisis.

 

This June 22, from 02:15 UTC, a resumption of Strombolian activity is observed at the level of the Southeast crater.
From around 02:30 UTC, a sudden increase in Strombolian activity is observed with the fall of the products on the external slopes of the CSE crater. In addition, the continuous emission of ash produced by the current activity, according to the forecast model, is dispersed in the NE direction.


Strombolian activity in the southeast crater turned into a lava fountain around 02:55 UTC. In addition, there is an overflow of lava to the southwest.


According to the images of the surveillance cameras, the INGV reports in its 04:13 UTC communication that the explosive activity at the Southeast crater has ceased, the lava overflow that extended in a southwest direction still seems weakly powered.
