Vulcano (Eolian Islands, Italy): Unrest continues at the volcano with little changes, according to the latest surveillance data published by the National Institute of Volcanology (INGV) in Catania, responsible for the monitoring of Etna and the Eolian Islands.
No significant changes occurred, however, during the past week. Even though parameters don't suggest an eruption might be imminent, head vulcanologist Prof. Mauro Coltelli was reported to mention to Italian press that chances of an eruption might be around 50:50.

The latest INGV report on Vulcano summarizes the latest data as follows:
- The temperature of the fumaroles in the crater and on its rims have remained stable, with values around 300-350 deg C for the hottest ones.


La Palma (Canary Islands (Spain)): Activity continues with little changes, but has been lower today. Lava supply to the latest sea entry seems to have stopped after it had grown to approx. 5 hectares in size by last night. Active lava flows on the surface are in the area la La Laguna, where at least one of the fronts continues to invade some of the remaining islands of uncovered land.

At the vents, mild fountaining and dense ash emissions continued most of the day, generating a plume that rose up to 4,300 m altitude and continued to drift towards the east coast, disabling operations at the airport. The situation is likely to remain like this for the next few days, unfortunately. While causing problems on the east coast, the westerly winds create relief with better air quality for the plagued Aridane valley and other areas of the western side of the island…

Volcanic tremor, and likely the flux rate of magma, have been at similar, overall comparably low values as yesterday. An interesting 3-D animation of the relief, both above and under water, and the current lava flow field can be seen in the following video:
