Activity at Guatemala's Fuego volcano has increased in the past days. Powerful strombolian explosions occur on average 8-10 times per hour and throw incandescent lava up to several hundred meters high. Ash rises more than 1 km above the crater and a near contiuous ash plume can be traced 15 SE. ...more

Bromo volcano exploded again late on 20 December, causing an ash plume rising to ca. 6000 m (20,000 ft) and drifting about 80 km south according to satellite data from the VAAC Darwin.
Tunguarahua continues to be very active. Frequent explosions produce ash plumes rising several kilometers, causig ash fall in the surrounding villages.

The ash emission from Bromo has been decreasing in the past days. The volcano still emits a plume to 400-800 m height comprising mostly steam and little ash. The Indonesian Volcanological Survey has downgraded its level to 3 (out of 4). A 2 km exclusion zone is still in place.

Merapi volcano (Central Java, Indonesia), update: ash threatens Jakarta airport, long haul flights cancelled
Strong eruptions continue at Merapi volcano, Indonesia. Violent explosions are audible tens of kilometers away from the summit. Magma is still rising inside the volcano and even more powerful explosions could occur. Ash from the explosions and from pyroclastic flows is forming a large plume reaching 10-20 km altitude and extending now over 300 km to the west. The ash threatens to reach the airspace of Jakarta airport soon, which promted Singapore Airlines, Lufthansa, Emirates and other airlines to suspend long-haul flights to Jakarta for the time being. ...more [read all]

Signals of a possible impending eruption at Grimsvötn volcano under the icecap of Vatnajökullremain remain uncertain. Scientist measured an increase in seismic tremor at Grimsvötn, probably caused by the meltwater flow increase, but no volcanic tremor. The composition of the meltwater indicates that much of the water has been melted caused by increased geothermal heat flow. No other signs of an impending eruption are detectable (so far).

The eruption of Merapi volcano seems to have produced its strongest explosion so far today this afternoon around 16-17h local time. According to satellite data from the Darwin VAAC, a large ash plume has been first detected at 09:47 UTC (=16h47 local time) reaching flight level 600, i.e. 60,000 ft or ca. 20 km altitude. ...more [read all]

Strong ash exlosions and the growth of the lava dome continue at Merapi volcano. Yesterday and today, several medium-sized pyroclastic flows reached up to 4 km distance into the river canyons of Kali Gendol, Lamat, Senowo, and Krasak. Several thousands of inhabitants not yet evacuated are reported to have fled the area in panic. Two persons dies in a related road accident.

Merapi volcano (Central Java, Indonesia), update: ash over Yogyakarta, pyroclastic flows and lava dome growth
The strong eruptions last night showered Ygoya and Sleman cities with ash. Andy reports directly from the observatory Babadan, + 1279 m on the western slope, still mostly free of ash: "I witnessed 2 times pyroclastic flows since at 05.00 through Senowo river. Again last night 29 oct, around at 24.00 there was a massive glowing ash column rising up until 1,5 km, and all people at 5 at the distance 10 km from the summit must evacuated. ...more

A powerful explosion happened at Merapi at 01h00 local time on 30 Oct 2010. News reports talk about an ash plume 12 km high.
Anak Krakatau started a new eruption, our volcanologist guide Doni reports from Indonesia. Explosions (near the summit?) created a new crater on its eastern side.
New explosions and pyroclastic flows occured today at Merapi volcano. An example of a pyroclastic flow triggered by material falling off the growing dome can be seen at a published Reuters press photo.
A paroxysmal eruptive phase occured on Shiveluch volcano on 27 October between 14h00 and 20h40 UTC. According to satellite data, an ash plume rose to at least 12 km (ca. 40,000 ft). ...more [read all]

As observed during our ongoing tour to Stromboli and Etna, the activity of Stromboli is characterized by high magma level inside the conduits and the the activity is concentrated at the NW and NE vents. The latter shows typical, mild strombolian eruptions at intervals of 15-20 minutes, throwing bombs to 50-150 m height. The NW vent, apparently filled with fresh lava to the top, is constantly spattering and lava is overflowing from near the top of the cone around the vent, creating an intra-crater lava flow, about 2-4 meters wide and 40m long, traveling west towards the center of the crater terrace. According to information from the mountain guides the flow must have started this morning (20 Oct 2010) or during the previous night. The monitoring team on Stromboli has not detected deformation of the Sciara del Fuoco or other signs that this event might be a predecessor of a possible new lateral eruption on the Sciara itself.

Our friend Michael Dalton-Smith flew over Lengai 10 Oct 2010 and snapped a few shots of the crater. There were some recent small lava flows inside the new crater. Also there we signs that new cone has had some more minor collapses on the inside. He could not tell 100%, but there looks like a small lava lake. ...more
