Bardarbunga (Central Iceland): Lava effusion continues at high rates and enlarges the lava field, now covering more than 84 square kilometers.
It has crossed the track Dyngjufjallaleið and stretched onto the older lava of Þorvaldshraun.
Lava is mainly flowing through a closed channel to the eastern edge of the lava field, about 15 km from the crater. Another tube system is transporting lava to the northern part.
Etna (Sicily, Italy): Explosions and ash emissions of moderate intensity continue from the Voragine crater.
During a visit of the front of the cooling lava flow of last paroxysm on the southern side of the New SE crater it was possible to see that the most advanced flow front is at 2130 m elevation in direction of M. Scavo.
Fogo (Cape Verde): The eruption seems to be coming to an end. There are no new reports of lava effusion or explosive activity at the vents since 8 January, when small strombolian explosions could still be observed.
Gas emission measurements show a clear decreasing trend as well, but it is still too early to declare the end of the eruption because the possibility of a new batch of magma rising from depth cannot be ruled out yet.
Kliuchevskoi (Kamchatka): Eruptive activity, strombolian explosions from the summit vent, has picked up during the past 1-2 days. A lava flow is now active on the southeastern flank and ash plumes have been reaching 28,000 ft (8.5 km) altitude. KVERT raised the volcano’s alert level to orange.
Incandescent material from the explosive summit activity is ejected to several hundred meters above the crater. Relatively intense ash emissions have been causing ash fall in up to 30 km distance to the west of the volcano.
Chirpoi (Kurile Islands, Russia): A thermal anomaly remains visible on cloud-free satellite images over Snow, a volcano of Chirpoi. The Aviation Color Code remained at Yellow.
Chirinkotan (Northern Kuriles): Minor activity persists at the volcano. A thermal anomaly over Chirinkotan was detected in cloud-free satellite images on 30 December. Aviation Color Code remains at Yellow.
Slamet (Central Java): PVMBG reported that during 1 November-5 January white plumes rose at most 1.5 km above Slamet’s crater. RSAM values fluctuated but decreased overall in December through 5 January.
Deformation and geochemical data showed no significant changes. The Alert Level was lowered to 2 (on a scale of 1-4) on 5 January. Residents and tourists were warned to not approach the crater within a radius of 2 km. (Smithsonian / USGS Weekly Volcanic Activity Report 31 December 2014-6 January 2015)
Tangkubanparahu (West Java): The volcano was placed on higher alert level (2 on a scale 1-4) on 31 Dec, as signs of volcanic unrest have recently been increasing (deformation, seismic activity).
An exclusion zone of 1.5 km radius around the crater is in place.
Hunga Tonga-Hunga Ha’apai (Tonga, Tonga Islands): The submarine eruption has apparently breached the surface. A steam and possibly ash plume was reported to have reached up to 30,000 ft (10 km) above sea level today and yesterday, New Zealand’s VAAC Wellington reported, based on pilots’ observations.
According to local news, the domestic Real Tonga airline cancelled some flights in the area. Unconfirmed reports mention ash fall on Ha’apai Island. An Air New Zealand flight bound to Tonga was diverted to Samoa.
Shishaldin (United States, Aleutian Islands): Seismicity at the volcano remains slightly elevated, but no signs of significant activity have been noted recently, only some steam emissions were observed occasionally. AVO maintains Aviation Color Code “Orange” and Volcano Alert Level “Watch”.
Fuego (Guatemala): During the past days, explosive activity has been relatively intense at the volcano.
Strong strombolian-type explosions have been occurring at rates of 6-8 per hour, sometimes ejecting incandescent bombs to more than 1000 m above the crater and producing glowing avalanches. Some of these reached the vegetation and caused small fires.
Ash plumes rose to 1-1.5 km above the crater and drifted 10-15 km to the west and southwest.
