Map of today’s active volcanoes

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 SW direction.
The full report is as follows: ERUPTION AT 20210919/1410Z ONGOING ASH EMISSION OBS VA DTG:01/2100Z to 10000 ft (3000 m)
…1 Oct:
With the eruption approaching two weeks of activity, there is no sign of it ending anytime soon. Instead, the magma supply rate seems to be more or less stable, judging from visible lava output and volcanic tremor, which remains at high levels.
The cone complex above the original eruptive fissure is showing signs of becoming more and more unstable, as several new effusive vents have been opening up during the past 12 hours or so.

At 10.15 a.m. local time this morning, observers on location reported seeing new gas and ash emerging from what is likely another vent forming at the NW base of the cone, visible in the attached pictures by the bluish haze behind the tree line, obviously coming from an area at the feet of the cone.
Over night, ash fall affected a wide area to the north of the site. It left a deposit of at least 1 cm in El Paso, but even in 15-20 km distance, a black layer of sandy ash has covered surfaces, forcing people to constantly clean roofs, solar panels and other surfaces.

…1 Oct:
The eruption continues with stable lava output, feeding several lava flows both near the vent and the main one that is supplying lava to the new ocean entry, which continues to grow slowly.
During most of today, southerly winds caused continuous ash fall in the area of El Paso and beyond, making driving etc difficult and the air filled with dust. At the vent, activity remains intense: vigorous lava fountaining with heights between estimated 50-100 m continued at the fissure vent on the NW lower flank, while several vents in the summit as well as two newly formed vents in between were producing pulsating, powerful and near-vertical jets of gas, ash and lava bombs. The vents are aligned along a northwest-southeast trending line, presumably reflecting the original eruptive fissure.

The cone itself is subject to frequent and sometimes dramatic changes. During the day, we observed increased steaming and dust rising from the northern flank of the cone complex and were speculating about new cracks opening as the cause resulting in movements of that flank. Later in the evening, two new fissures opened on the NW flank and rapidly emitted two new lava flows that quickly descended parallel to the north of the existing flows, covering and burning additional land, probably including other so far untouched buildings in the evacuation zone.
The new eruptive fissures we observed are in the line of the other vents and below the main lava fountaining vent.

Suwanose-jima (Ryukyu Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Tokyo warned about a volcanic ash plume that rose up to estimated 11000 ft (3400 m) altitude or flight level 110 and is moving at 15 kts in S direction.

Lewotolo (Lesser Sunda Islands): (1 Oct) Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Darwin warned about a volcanic ash plume that rose up to estimated 8000 ft (2400 m) altitude or flight level 080 and is moving at 15 kts in W direction.

Kilauea (Hawai’i): (1 Oct) Geologist Philip Ong from our team on Hawai’i published the following summary of the start of the new eruption on Hawai’i on Hawaii Tracker:
New eruptive fissures opened inside Halemaʻumaʻu crater at Kīlauea volcano’s summit at 3:20pm on Wednesday, September 29th, 2021, and by this next morning have filled the crater with approximately 60 feet, or 18 meters of additional lava, covering an area of 112 acres or 45 hectares.

The lava lake, crusted and cooling since the end of the most recent eruption in May, finally seems poised to rise enough to be visible to visitors from public overlooks within Hawaiʻi Volcanoes National Park, where the eruption is wholly contained and posing little threat to people apart from its gas.
Following last month’s intrusion under the south caldera, seismic activity dwindled even as ground inflation quickly resumed, suggesting that magma continued to supply to the volcano from below without interruption. Finally, the volcano reached a breaking point, suddenly expressing a quick rise in ground tilt along with a swarm of earthquakes, the largest of which registered as a magnitude 3.1, and within an hour lava was spotted at the surface by USGS Hawaiian Volcano Observatory webcams. The USGS correspondingly raised Kīlauea’s alert status, first from Yellow/Advisory to Orange/Watch, and shortly thereafter to the current Red/Warning level.

Semisopochnoi (United States, Aleutian Islands): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Anchorage warned about a volcanic ash plume that rose up to estimated 8000 ft (2400 m) altitude or flight level 080 and is moving at 10 kts in S direction.
