INGV reported that eruptive activity at Etna?s summit craters continued during 25 November-1 December.
Strombolian explosions at Voragine Crater (VOR) occurred at intervals of 5-10 minutes, and many incandescent jets rose above the crater rim.
Some explosions created incandescent flashes in emissions rising above the crater rim.
A cone which had started forming on the crater floor in mid-September had continued to grow according to observations by field guides.
Sporadic ash emissions began at New Southeast Crater (NSEC) on the evening of 30 November, and a single Strombolian explosion was recorded on 1 December.
Incandescence from Bocca Nuova Crater was intermittently visible at night.
