Strombolian activity from Etna yesterday early morning (image: INGV-OE Catania)
The volcano entered a new eruptive phase yesterday.
A vigorous eruptive activity has intensified at two of Etna’s four summit craters, the Northeast Crater and Bocca Nuova. Strombolian explosions are generating jets of incandescent material along with minor ash emissions.
Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 7000 ft (2100 m) altitude or flight level 070 . The full report is as follows:
