Vulcano (Eolian Islands, Italy): (2 Oct) The observatory Istituto Nazionale di Geofisica e Vulcanologia (INGV) reported that elevated fumarolic activity in the Fossa summit crater has been detected today.
The activity is associated with increased level SO2 and CO2 emissions and temperature.

La Palma (Canary Islands (Spain)): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 10000 ft (3000 m) altitude or flight level 100 and is moving at 10 kts in S direction.
The full report is as follows: ERUPTION AT 20210919/1410Z ONGOING ASH EMISSION OBS VA DTG:02/1500Z to 10000 ft (3000 m)
...2 Oct:
Yesterday's satellite image shows beautifully the circular eruption plume from the ongoing eruption, generating concentric wave patterns due to the absence of wind in combination with the rising column of ash and hot air from the eruption.
It also shows a typical weather pattern for the island: The normal north-east trade winds near the ground caused a cloud barrier east of La Palma, leaving the west side free of clouds. Above a first inversion layer, located between 600-800 m elevation, there is a southeast wind current from the Sahara, carrying extra dust (in addition to the ash from the volcano), known as "Calima", which is confined again by a second inversion layer at around 1600 m.
During this weather, the temperatures on the coast are moderate (last night near Tazacorte: 18-19 deg C) and above the lower inversion layer and the upper layer, where many villages are located, the temperatures are much higher: last night, in the caldera, they reached 31 deg and 26-28 deg on the NW flanks where we are currently located.
...2 Oct:
The eruption continues with no significant changes during the night. The upper vents produce pulsating fountains of ash and some lava, while the lower vents erupt more degassed lava in low lava fountains or directly as lava flows.
Volcanic tremor remains stable at moderate to high levels. The ash plume today is rising several 100 m and drifting west with the trade winds.
...2 Oct:
The eruption continued without significant changes during the day of Oct 1st. Lava fountaining from several vents aligned in the upper part of the crater continued at fluctuating intensity, producing a weak ash plume, which nevertheless rose to approx. 1 km and spread laterally in the absence of wind, gradually filling the valley with a thick layer of dust.
From the lower vents at the crater, several lava flows continued to flow down-slope, most notably from the two vents that had opened yesterday and earlier today.

Suwanose-jima (Ryukyu Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 12000 ft (3700 m) altitude or flight level 120 and is moving at 15 kts in SW direction.
The full report is as follows: VA EMISSIONS CONTINUING OBS VA DTG:02/1720Z to 12000 ft (3700 m)

Lewotolo (Lesser Sunda Islands): (2 Oct) The volcano continues to produce occasional strombolian activity.
The explosive eruption occurred from its crater at 22:50 local time today accompanied by ejected scoria at about 300 m-600 m distance from the summit.

Kilauea (Hawai'i): (2 Oct) The effusive eruption of the volcano continues and remains active within the Halemaʻumaʻu crater.
Fountaining continues at two locations, from several vents stretching from the lake's center to its southern margin and from the western wall of the summit crater.
