Etna (Sicily, Italy): In the past weeks, Etna has been more or less calm. Today, small intermittent explosions resumed at the North-East crater, the volcano observatory in Catania (INGV) reported.
According to a report, these explosions began at 11.16 a.m. local time and have been producing small ash plumes that dispersed quickly in the area of the summit craters. Volcanic tremor shows no significant variations and remains at low to medium levels.
Apart from this, the Bocca Nuova seems to be the most active crater at the moment, producing dense steam plumes with some pulsating activity as can be seen in the image attached.


Vulcano (Eolian Islands, Italy): The volcanic unrest on the small island has increased and the scenario of new volcanic activity is considered to be more likely now.
As a response, the Sicilian government's Civil Defense unit decided to raise the alert level of the volcano from “yellow” to “orange” and declard the state of crisis and regional emergency for the island of Vulcano, in order to activate a range of measures aimed at protecting the population potentially threatened by volcanic hazards in case of volcanic explosions or a further increase in gas emissions.

La Palma (Canary Islands (Spain)): The eruption continued at similar intensity as yesterday, although lava activity seems to have been a bit lower. There were alternating phases of fountaining and ash plumes rising to around 10,000 ft (3,000 m) and quieter phases with mainly steaming at the vents. A change of wind brought the ash fall again to the northeast side of the island, where the airport Mazo had to shut down.
The lava surge of the past days had created several new surface flows starting at or near the vents at the cone, forming a complex system of more or less parallel flows on top of the existing flow field. By yesterday, they had reached the area between La Laguna and Todoque. The northernmost one seems to be the most voluminous of them. Already yesterday, it had reached the so-far spared area between the two parallel lava arms between Montaña Laguna and Montaña Todoque, destroying additional land and structures. The other surface lava flows have so far remained on top of existing flows and are scattered in the area of Todoque.
