Eruption still going this morning. Lave has now filled 440ft of the bottom of crater. Two vents are now under the lake and if it continues it's other vent is likely to follow.

Still chugging away the lava lake is now 554ft deep. Going to be interesting to see how far it fills the caldera.

KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: Lava activity is confined to Halemaʻumaʻu with lava erupting from vents on the northwest side of the crater. Monday afternoon (Jan. 4), the lava lake was 191 m (627 ft) deep and perched above its edge. SO2 emission rates were still elevated.

Summit Observations: Sulfur dioxide emission rate measurements made on Sunday (Jan. 3) were still in the range 3,000-6,500 t/d since last Sunday (Dec. 27)--the same range of values that was common for emissions from the pre-2018 lava lake. Summit tiltmeters recorded weak deflationary tilt since Jan. 1. Seismicity remained elevated but stable, with steady elevated tremor and a few minor earthquakes.

East Rift Zone Observations: Geodetic monitors indicate that the upper portion of the East Rift Zone (between the summit and Puʻu ʻŌʻō) contracted while the summit deflated at the onset of this eruption. There is no seismic or deformation data to indicate that additional magma is currently moving into either of Kīlauea’s rift zones.

Halemaʻumaʻu lava lake Observations: The west vents spattered from the top of a small cone plastered on the northwest wall of Halemaʻumaʻu crater. This morning, lava is flowing down an narrow channel to the lake and feeding a small dome fountain in front of the west vents probably from a submerged portion of the vent.

The lava lake was 191 m (623 ft) deep Monday afternoon (Jan. 4) and had a volume of about 26 million cubic meters (34 million cubic yards). The most recent thermal map (Dec. 30) provided the lake dimensions as 800 by 530 m (875 by 580 yds) for a total area of 33 ha (82 acres) (https://www.usgs.gov/maps/december-30-2020-k-lauea-summit-eruption-thermal-map). The lake is now perched about a meter (yard) above its narrow edges as measured Sunday morning (Jan. 3); overflows onto the narrow edge slowly elevated a low wall around the lake similar to the wall around an above-ground swimming pool.

The main island of cooler, solidified lava floating in the lava lake continued settling, mostly rotating counter-clockwise, in front of the west lava source filling the lake, while the 11 smaller islands moved a bit but remained in the east end of the lake. The main island measured about 250 m (820 ft) in length, 135 m (440 ft) in width, and about 3 ha (7 acres) in area based on the Dec. 30 thermal map. Measurements Friday afternoon (Jan. 1) showed that the island surface was about 6 m (20 ft) above the lake surface. Yesterday afternoon, (Jan. 4), the island was measured as 1-2 m (1-2 yds) higher above the lake surface.

Hazard Analysis: High levels of volcanic gas, rockfalls, explosions, and volcanic glass particles are the primary hazards of concern regarding this new activity at Kīlauea’s summit. Large amounts of volcanic gas—primarily water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2)—are continuously released during eruptions of Kīlauea Volcano. As SO2 is released from the summit during this new eruption, it will react in the atmosphere with oxygen, sunlight, moisture, and other gases and particles, and within hours to days, convert to fine particles. The particles scatter sunlight and cause the visible haze that has been observed downwind of Kīlauea, known as vog (volcanic smog), during previous summit eruptions. Vog creates the potential for airborne health hazards to residents and visitors, damages agricultural crops and other plants, and affects livestock operations. Rockfalls and minor explosions, such as the ones that occurred during the 2008–2018 lava lake eruption at Kīlauea summit, may occur suddenly and without warning. This underscores the extremely hazardous nature of Kīlauea caldera rim surrounding Halemaʻumaʻu crater, an area that has been closed to the public since late 2007. Pele's hair and other lightweight volcanic glass fragments from the lava fountains within Halemaʻumaʻu will fall downwind of the fissure vents and lava lake, dusting the ground within a few hundred meters (yards) of the vent. High winds may waft lighter particles to greater distances. Residents are urged to minimize exposure to these volcanic particles, which can cause skin and eye irritation similar to volcanic ash.

The Hawaiian Volcano Observatory (HVO) continues to closely monitor Kīlauea’s seismicity, deformation, and gas emissions for any sign of reactivation, and maintains visual surveillance of the summit and the East Rift Zone. HVO will continue to issue daily updates and additional messages as needed.

KILAUEA VOLCANO (VNUM #332010)
19°25'16" N 155°17'13" W, Summit Elevation 4091 ft (1247 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Activity Summary: Kīlauea Volcano is erupting. Lava activity is confined to Halemaʻumaʻu with lava erupting from a vent on the northwest side of the crater. Yesterday evening, January 18, the lava lake was about 202 m (663 ft) deep and remains stagnant over its eastern half. SO2 emission rates remain elevated.

Summit Observations: The most recent sulfur dioxide emission rate measurements from January 14, show an increase to about 4,700 t/d—within the range of emission rates from the pre-2018 lava lake (3,000–6,500 t/d). The summit tiltmeters recorded neither inflation or deflation over the past few days. Seismicity remains elevated but stable, with steady elevated tremor and a few minor earthquakes.

East Rift Zone Observations: Geodetic monitors indicate that the upper portion of the East Rift Zone (between the summit and Puʻu ʻŌʻō) contracted while the summit deflated at the onset of this eruption. There is no seismic or deformation data to indicate that additional magma is currently moving into either of Kīlauea’s rift zones. SO2 and H2S emissions from Puʻu ʻŌʻō were below instrumental detection levels when measured on January 7.

Halemaʻumaʻu lava lake Observations: Low fountaining from the west vent supplies a channel of lava which is pouring into the lava lake within Halema‘uma‘u crater.

The active western half of the lava lake was about 202 m (663 ft) deep yesterday evening (Jan. 18) while the stagnant eastern half of the lake remains several meters (yards) lower. The whole lava lake—including the stagnant eastern half—is perched at least 1–2 m (yards) above the crust between the perched lake and the crater wall.

All of the islands have been stationary over the past week, frozen in the eastern stagnant portion of the lava lake. The dimensions of the main island remained unchanged with its edges several meters (yards) above the lake surface. On January 12, the west end of the island was measured as 8 m (26 ft) above the lava lake surface, with the highest point at 23 m (75 ft) above the surface.

Etna has had quite a substantial eruption this evening..

 

[Snipper]

Anyone sussed out the precise location of the vent?  Been to Etna when damn all was happening so interested where the action is at the moment. Been trawling. All a bit vague so far just it is the SE crater. 

[The PIT]

Etna has had a violent eruption on the night of the 22nd and 23rd February

Typical I missed it. The source of the eruption is the new se crater.

One hell of a show now seems to be dying down

Next one Saturday allowing 36 hours between the eruptions??

[The PIT]

No signs of life on Etna at the moment however if the trend is going to continue I suspect tomorrow will see the next display. Its all possible that it has finished it's present sequence.

[The PIT]

Kilauea still chugging away with its summit lava lake. Meanwhile Etna smoking merrily so tonight could see a show.
