Etna volcano update: Bush fire in Valle del Bove raising speculations of new vent

Residual activity at the New SE crater and bright glow from a vast bush fire near Monte Rinato last evening

Weak activity continues last night at the New SE crater, with weak lava flow emission from the eastern end of the main eruptive fissure, but gradually ceased during the night.
Volcanic tremor has again decreased to low levels.
A significant bush fire started during the peak phase of yesterday’s activity in the Valle del Bove near or on the southern slope of Monte Rinato. Initially, the appearance of fumes from this area raised speculations of a possible new vent in the Valle del Bove, but soon were discarded.

The cause of the fire remains speculative, but most likely, it was ignited by an exceptionally far-traveled hot volcanic bomb that landed in an area of dense, dry vegetation yesterday. As of this morning, the fire seems to have exhausted itself as no more fumes could be seen, while bright glow was visible last night (see picture).

During the whole time over the past days, intermittent strombolian explosions producing ash plumes rising a few 100 meters have been continuing from the main vent in the central Voragine summit crater. Presumably, mild strombolian activity also continues in Bocca Nuova, while the North-East crater produces dense gas and steam clouds only, but no visible incandescence.
