Stromboli returns to make itself felt with a new lava overflow which is spectacular and is clearly visible from the nearby islands of Panarea, Salina and Stromboli. The National Institute of Geophysics and Volcanology, Etna Observatory, has communicated that from the analysis of the images of the surveillance cameras, since late yesterday morning, a lava overflow has been observed in progress from the North crater area, which is feeding a lava flow in the upper part of the Sciara del Fuoco and which at the moment does not yet reach the sea.
The overflow is accompanied by modest but continuous spattering activity from at least two vents in the northern crater area and is causing the sliding of hot material on the Sciara with the formation of puffs of dark dust and the rolling of hot blocks. Puffs of ash that the wind tends to push towards the village of Ginostra. In the southern crater area, however, activity is continuing regularly with the classic so-called “Strombolian” summit explosions.
“From a seismic point of view – the INGV experts say – there are no significant changes evident even if in the last few hours some small landslide events have been recorded along the Sciara del Fuoco.” However, the volcanic tremor did not show significant variations and the analysis of data from the ground deformation monitoring networks does not reveal any particular variations. Meanwhile, in these days, work on the Stromboli radio monitoring network and the installation of new instruments are being concluded.
Remaining in Stromboli, it should be noted that yesterday, following a violent downpour, some streams along the island’s streets overflowed again in Ginostra.
