A sudden above-average eruption took place from the volcano’s vent in the Northern crater area yesterday evening, the INGV reported.
At 19:06 UTC, the major explosion thrown incandescent lava bombs and lapilli to the upper Sciara del Fuoco.
The strong eruption triggered at least two lava overflows onto the outer slope, of which its fronts appeared to be stationary yesterday.
A sharp spike in tremor (19:05 UTC) accompanied the eruption onset that later culminated in high amplitude tremor values.
The activity of the volcano had continued at fluctuating levels within the last week so far, characterized by periods of short-lived intense spattering and small lava flows. Events like yesterday are nothing unusual on the volcano and occur from time to time, but rarely more frequently than every few months or so.
