Chaitén volcano experienced an increase in activity over the past few weeks. Yesterday, around 11 am local time on 19 Feb., a largere section of the growing lava dome in the crater collapsed, triggering a large pyroclastic flow that came close to the already largely abandoned town of Chaitén. According to press reports, heavy ash falls occurred in the area and the evacuation of the remaining residents of the town is under way. ONEMI reports the eruption of a considerable column of ash. ...mehr [alles lesen]

A new eruption started at Galeras volcano in south-western Colombia on 14 Feb. 2009. INGEOMINAS reported an ash explosion at 19h10 local time accompanied by a strong pressure wave, strong ash fall and release of large quantities of sulphur dioxide gas. The city of Pasto and nearby areas suffered from ash fall, but no fatailities or accidents have been reported caused by the eruption. ...mehr

There are strong eruptions being reported from the summit crater of Asama volcano in Japan. There is a high ash column and ash was driven by wind even to Tokyo.

Redoubt volcano, Alaska, USA, activity updates: hot steam & melting galciers - near eruption possible!
It is reported that there is a whole which hot steam comming out. The glaciers have started to melt down. A near erupion is possible. The last eruption of Redoubt volcano took place in 1989.

The volcano Redoubt in Alaska is very close to an eruption. The Alaska Volcano Observatory reports that there are increasing seismic levels. Until now there is no eruption visible. The staff of the observatory is watching the volcano on a 24 hours base. The alert level is at orange, what is a serious sign for a near eruption. The ice covered volcano may cause lahars and later eventually even pyroclastic flows (?). The situation is surely dangerous after the experience USA made with Mt. St. Helens.

On 11 January there was an ash plume at Ubinas that was rosing to an altitude of 7.3 km.
There was a explosion at Suwanose-jima on 9 January.
It was reported that there was higher seismic activity at Shiveluch during the time of 2-9 January and ash plumes rose to an altitude of 8.8 km. There was also a daily thermal anomaly on the lava dome and ash plumes, what is a sign of lava dome growing.
The Tokyo VAAC reported that on 9 January there was an eruption at Sakura-jima that produced a ash plume.
It was reported that there were ash emissions and gas plumes from cones inside Llaima's crater at 30 December-6 January.

It was reported that there was high seismic activity at Kliuchevskoi during 1-9 January. There was Strombolian activity and lava effusion on the NW flank. Satellite imagery shows a large daily thermal anomaly in the crater. Also ashfall was reported in Kozyrevsk village.
It was reported that during 7-13 January lava flowed through a tube system from underneath Kilauea's Thanksgiving Eve Breakout and reached the Waikupanaha ocean entry. Surface flows were noted and incandescence was seen at pali. Explosions at the ocean entry were seen.The vent in Halema'uma'u crater continued to produce white plumes. The sulfur dioxide emission rate at the summit was 800 tonnes ...mehr
During 2-9 January there were no seimsic data available from Karymsky due to technical issues. Satellite imagery revealed a thermal anomaly in the crater on 7 January.
It was reported that during 8-9 January, there were explosions on Fuego that produced ash plumes. Constant avalanches of blocks descended from the volcano.
It was reported that during 5-11 January activity from Etna's summit craters was observed, but bad weather prevented direct inspection of the summit area. Degassing was seen from the NW Bocca Nuova vent, from the walls and floor of Southeast Crater, and along summit fumarolic fields. The fissure E of the summit craters continued to produce active lava flows until the end of the fissure, along the W wall of the Valle del Bove.
Satellite imagery shows, that on 7 January ash plumes from Dukono rose to an altitude of 1.8 km and drifted E and SE.
It was reported that during 29 December-9 January Chaitén's lava dome continued to grow. Plumes rose to altitudes of 2.6-3.1 km. Block-and-ash flows from frequent spine collapses fell down from the edge. ...mehr
Satellite imagery reported that on 7 January ash plumes from Batu Tara rose to an altitude of 2.4 km and drifted NE and ENE.
Satellite imagery reported that during 7-8 and 10-11 January ash plumes from Barren Island were seen.
A pilot observation reported that an ash plume from Yasur was seen.
It was reported that during 7-12 January there were visible steam-and-ash plumes from Tungurahua, ash fell within 8 km and roaring, explosions, and "cannon shot" noises were reported. Also incandescence blocks were ejected from the crater and rolled down the flanks.
It was reported that during 2-3 January activity from the Soufrière Hills lava dome increased drastically. On 2 January, a pyroclastic flow traveled down to Tyers Ghaut (NW) and to to the upper part of Belham River. On 3 January two explosions produced ash plumes to high altitudes and ashfall affected most of the island The strong explosions reached to at least 500 m above the dome. In-column collapses resulted in pyroclastic flows. The level of activity decreased dramatically after the second explosion.
It was reported that thermal anomalies over Shishaldin's summit were visible on in satellite images during 7-10 January.
3-14 January ash plumes from Rabaul rose to altitudes of 1,7 km. Explosions and incandescence were visible. There were no flights by Air Niugini because of ash fall until 13 January. On January 11 two vents opened at the SW flank.

The eruption of Mount Etna in Sicily, initiated on 13 May 2008, is continuing into the new year and is thus "The 2008-2009 eruption" of this volcano. Lava continues to issue quietly from the lower end of an eruptive fissure on the upper east flank, feeding several short incandescent lobes. The activity is going on like this since many months, and shows no signs of ending soon. --- ...mehr [alles lesen]
