Etna volcano update: Intermittent strombolian activity from New SE crater

After a period of mild activity during the last days of April, the volcano had been again calm until yesterday evening, when intermittent mild strombolian activity returned once again to the New SE crater.

Current values of volcanic tremor are low, not suggesting that the activity is about to increase any time soon. It is open to speculation whether the series of particular violent lava fountain episodes during Feb-early April have now emptied the reservoir that contained eruptible magma for good, at least for the time being, and the volcano will stay relatively calm for some time now.
It is unclear whether the activity in the other summit craters (Bocca Nuova, Voragine and NE crater) still continues; it had been largely unaffected by the activity of the New SE crater and had been going on at fluctuating intensity for many months. Thermal anomalies are still present in at least some of the other vents, suggesting that mild intra-crater activity is still present, but the current near-total absence of visitors and direct observations make it difficult to know for sure.

A swarm of small earthquakes has been occurring under the volcano since yesterday: about 50 tiny quakes with magnitudes between 1.0 and 2.2 were detected over the past 24 hours in an area on the lower eastern flank, roughly between the towns of Milo, Mascali and Giarre. ... Read all
