An explosion occurred this morning and produced a plume that rose to approx 5 km altitude and drifted 80 km to the northeast before dissipating.
Sun, 30 Nov 2014, 15:323 strong explosions occurred during yesterday-today, producing ash plumes that reached up to 16,000 ft (4.8 km) altitude (Tokyo VAAC)

The eruptive vents at Fogo this morning (MuzikaTV)
Although explosive activity has decreased at the vents, it seems that lava effusion picked up. The advance of some of the lava flow fronts in Portela village picked up again this morning, reaching 20 meters per hour. Local sources mention that seismic activity also increased.
after their recent field expedition. As the lava field continues to expand, new branches of red hot rivers reach its edge and cascade down on the sandy plain below in a spectacular 'water'fall of glowing lava. Scientists report that by now the Holuhraun lava field covers almost 75 square kilometres which represents an area bigger than the Reykjavik metropolitan area.

The lava lake at the summit of Nyamuragira volcano in DR Congo.Photo: Benoit Smets
For the first time in 75 years, a new lava lake appeared on some of Africa's most active stratovolcanoes: Mount Nyamuragira in the Democratic Republic of Congo. The neighbouring volcanoes of Nyamugira and Nyiragongo are both part of the Virunga volcanic chain in the East African Rift, situated along DR Congo's border with Rwanda. They are famous as two of the few volcanoes on Earth that have sustained lava lakes for several decades. The previous lava lake at Nyamuragira emptied in 1938 as its lava poured out of the summit and flowed more than 30 kilometres down to Lake Kivu. The new lava lake seems to have formed at the bottom of the 500 m deep crater that was left behind by this 1938 lava flood.

Explosive activity at the eruptive vents of Fogo on 25 Nov 2014 (MuzikaTV)
:
(25 Nov) The eruption continues, but the situation is critical inside the Cha caldera. The northern lava flow branch has started to enter the village of Portela and today destroyed and/or damaged several buildings, including the headquarters of the Fogo Nature Park.

Incandescence at Nakadake crater (JMO)
Activity from the Nakadake crater has intensified. Since yesterday, ash emissions and comparably strong incandescence have been observed, suggesting that a new magmatic eruption could be under way.

AVO reported that although seismicity at Shishaldin continued to be elevated, levels declined during 26 November-2 December. Elevated crater temperatures were detected in satellite images during periods of clear weather from 26 to 28 November. A low-level lava eruption was likely still occurring within the summit crater of the volcano.

Wed, 26 Nov 2014, 06:00KVERT reported that during 21-27 November lava-dome extrusion onto Sheveluch's N flank was accompanied by incandescence, hot avalanches, and fumarolic activity. Strong explosions at 1021 on 23 November and 0328 on 26 November generated ash plumes that rose to altitudes of 8-9 km (26,200-29,500 ft) a.s.l and drifted 400 km NE and 200 km SE, respectively. Satellite images detected a thermal anomaly over the dome during 22-23 and 26-27 November; cloud cover prevented views of the volcano on the other days.

Wed, 26 Nov 2014, 06:00During 26 November-2 December HVO reported that Kilauea's 27 June NE-trending lava flow continued to be active. During an overflight on 1 December volcanologists observed a narrow lava flow that had originated from the W edge of the flow field and traveled 2.8 km N, burning vegetation along its path. They noted that weak surface activity was present in three areas upslope: the W side of the flow field that had produced the new lava flow, the E edge of the crack system, and at a breakout 3.5 km upslope of Pu'u 'O'o.

INSIVUMEH reported that during 28-30 November explosions at Fuego produced ash plumes that rose at most 1.2 km above the crater and drifted as far as 25 km S, SW, and W. Shock waves from some of the explosions rattled structures near the volcano. Incandescent material was ejected 100-150 m above the crater duirng 29-30 November.

During 26 November-2 December, IMO maintained Aviation Colour Code Orange due to continued activity at Bárdarbunga's Holuhraun eruptive fissure. Based on a field report from 25 or 26 November the activity was characterized as pulsating; lava surged from the vent for 2-3 minutes, every 5-10 minutes, causing bulges in the upper parts of the lava channel. Measurements obtained during an overflight on 26 November indicated that the total amount of subsidence of the Bárdarbunga Caldera was about 50 m, with an estimated volume of 1.4 cubic kilometers.
