Map showing the location of the lava flow near Pahoa as of 30 Dec 2014 (HVO/USGS)
The front of the the June 27th lava flow remains stalled at 530 m from the Pahoa Marketplace, but during yesterday's overflight, several small breakouts were seen active immediately upslope from the front.

SVERT reported that satellite images over Snow, a volcano of Chirpoi, showed a thermal anomaly on 4 January. Cloud cover obscured views on other days during 30 December-5 January. The Aviation Color Code remained at Yellow.
Wed, 31 Dec 2014, 06:00INGV reported that on 29 December, a day after a short but intense eruption, cameras viewing Etna recorded small ash emissions from New Southeast Crater (NSEC) and persistent glow from the saddle between the old and new SEC cones at dusk. During the night on 1 and 2 January cameras recorded intermittent flashes from Voragine Crater (one of four summit craters), indicating Strombolian activity there for the first time in nearly two years. At 0530 on 2 January explosions at NSEC generated ash plumes that drifted SW.

Based on gas-monitoring efforts of the Instituto Vulcanológico de Canárias (INVOLCAN) and data from the Toulouse VAAC, the Observatório Vulcanológico de Cabo Verde (OVCV) reported that sulfur dioxide emission rates at Fogo were 1,201-1,368 tons per day during 30-31 December and 1-2 January. A gas plume rose 700-900 m above the cone during 30-31 December and drifted N; on 31 December tephra was ejected 30-40 m away and ash was present on the plume. A lava front near S Ilhéu de Losna had been stagnant for a few days while one near the N part of the town advanced at a reduced speed, overtaking a road and parts of some housing.
Wed, 31 Dec 2014, 06:00Based on a pilot observation, the Wellington VAAC reported that an ash plume from Hunga Tonga-Hunga Ha'apai rose to an altitude of 3 km (10,000 ft) a.s.l. on 6 January.

Based on seismic data from KB GS RAS, KVERT reported that seismic activity at Klyuchevskoy began to increase during 19-20 December and then increased again on 31 December. Although cloud cover prevented views of the volcano during 31 December-1 January, a thermal anomaly was detected in satellite images on 1 January, possibly indicating that a Strombolian eruption had begun. The Aviation Color Code was raised to Yellow on 2 January.
Wed, 31 Dec 2014, 06:00BNPB reported that an eruption at Soputan began at 1447 on 6 January. Observers at a nearby post reported a dense gray-to-black ash plume rising about 6.5 km above the summit and drifting ESE. Lava flows traveled 2 km down the WSW flank.

PVMBG reported that white plumes rose at most 50 m above Tangkubanparahu's Ratu Crater during October-December 2014. Deformation data showed changes and seismicity increased. On 31 December the Alert Level was raised to 2 (on a scale of 1-4).

During 30 December-6 January HVO reported that Kilauea's 27 June NE-trending lava flow continued to be active with breakout lava flows upslope of the leading front. A narrow lobe of lava that had broken away from the W edge of the flow field below the crack system stalled and by 30 December the front was about 800 m above the intersection of Pahoa Village Road and Highway 130, and 530 m from the Pahoa Marketplace.

Wed, 31 Dec 2014, 06:00CENAPRED reported that during 31 December-6 January seismicity at Popocatépetl indicated continuing emissions of water vapor and gas, which occasionally contained ash. Cloud cover sometimes prevented views of the crater. Incandescence from the crater was visible on a few nights.

KVERT reported that during 27 December-2 January lava-dome extrusion onto Sheveluch's N flank was accompanied by incandescence, hot avalanches, and fumarolic activity. Strong explosions on 26 and 29 December generated ash plumes that rose to altitudes of 6-9 km (19,700-29,500 ft) a.s.l. and drifted 60 km W and 370 km ENE respectively.

Wed, 31 Dec 2014, 06:00AVO reported that seismicity at Shishaldin continued to be slightly elevated over background levels during 31 December-6 January. Nothing significant was observed in partly-to-mostly cloudy satellite and web camera images. Minor steam emissions were occasionally recorded by the webcam.

BNPB reported that an eruption at Sinabung occurred during 0833-0919 on 3 January; this event was larger than the events that had been occurring almost daily. Pyroclastic flows traveled 2-4 km down the flanks and ash plumes rose as high as 3 km. Ashfall was reported in Payung (5 km SSW), Tiganderket (7 km W), Selandi (5 km SSW), Juhar (20 km SW), and Laubaleng (35 km WSW).
