Vents in the crater of Stromboli as of Oct 2018 (INGV Catania)
Our tour leader Marco Fulle visited the volcano yesterday along with a small group on our ongoing Stromboli to Etna tour and reported that they saw more than 100 eruptions from various vents in total, during the 90 minutes they stayed on the top!
INGV Catania summarized the activity for the past week: The N1 (northeastern) vent produced explosions of varying intensity from low (less than 80 m high) to medium (less than 150 m high) levels, ejecting with coarse incandescent material (lapilli and bombs) and minor ash. While the adjacent N2 vent is less active, it also shows explosions of varying intensity from 40-120 m ejection heights, but more rich in ash. The frequency of eruptions from both northern vents ranged between 3-11 events/hour.´
The central vent C has two emission points and continues to show constant degassing. The vents in the northwestern and southern crater area (nor labelled S1, S2) showed strombolian activity at similar rates as the northern vents:
Vent S1 and S2 both produced jets of incandescent material of low to medium intensity (80-120 m). The frequency of the explosions from the CS area has been variable between 10 and 20 events/hour.
