Map of today’s active volcanoes

Etna (Sicily, Italy): 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).

…1 Mar:
The latest lava fountaining episode, or paroxysm, occurred in the morning of Sunday 28 Feb 2021, after a longer interval than the previous 7 ones. After roughly three and a half day, the awaited number 8 episode of the current series of paroxysms occurred Sunday morning around 9 am local time.
Different from the previous ones, the activity increased from very low levels to strong lava fountains in an extremely very short time. First signs of reactivation of the New SE crater showed themselves around 8:40 am, with the appearance of strombolian bursts and a lava flow from the eastern summit vent.

This activity increased to lava fountaining within approx 30 minutes and had already reached the peak phase at around 9:20 am.
At that time, a tall eruption column rose several kilometers above the volcano’s summit and spread into a large umbrella cloud similar to the preceding eruptions.

Volcano Activity Summary for 1 Mar 2021:

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

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.
