Vulcano (Aeolian Islands, Italy): Volcanic unrest continues at the volcano. Some of the latest monitoring parameters show an increase while others have remained more or less stable, according to the Catania Volcanoes Observatory.
The microseismic activity as well as the temperatures of the fumaroles at the level of the crater and the emissions of carbon gases and sulfur dioxide remained high while no new changes in soil deformation were found.

La Palma (Canary Islands (Spain)): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse has warned of a volcanic ash plume that rises to an estimated altitude of 11,000 feet (3,400 m) or flight level 110 and is moving at 5 knots in the direction NOT.
The full report is as follows: ERUPTION AT 20210919 / 1410Z OBS ASH EMISSION VA DTG: 31 / 2100Z at 11000 ft (3400 m)

UPDATE: the earthquake has been increased to a 5.0 magnitude event; Judging by the large number of users talking about it, it might just be the biggest event yet.
Original report:

… October 31:
The latest government information indicates that seismic activity is declining while magma production remains very high. Sulfur dioxide emissions decreased for the 5th consecutive day but remain very high. On the contrary, emissions of volcanic CO2 (carbon dioxide) have increased.

… October 31:
Scientists from INVOLCAN documented several volcanic flashes seen in the eruption column.
In recent days, these have become more frequent. This goes hand in hand with the observed increase in explosive behavior at the vents – more material is shattered into ash (as opposed to liquid lava fountains) and the resulting particles are likely finer as well.

… October 31:
Eruptive activity remains high, dominated by heavy ash emissions reaching up to 18,000 feet (5.5 km) elevation today, but luckily drifting west over the Atlantic Ocean and sparing the airport. Local sources reported that loud explosions could be heard overnight. The eruption became more and more “ashy”, or explosive, at least as far as what we can see at the vents:
At the active cone, the emission of incandescent and fluid lava from fountains and lava flows is less intense compared to previous days, but the volcanic tremor remains very high, suggesting that the effusion rate has not declined. The most likely explanation is not that the activity has decreased, but that most of the fluid lava that has erupted is diverted directly into a lava tube system and mostly remains hidden from view, until it emerges somewhere downstream to feed surface flows above older flows or create new languages ​​of active flow along its margins.
