Activity has increased during the past days. A new small lava flow started on 14 June on the southern flank and had a length of 300 m this morning. ...mehr
Explosive strombolian activity has picked up a bit as well. Glowing tephra is ejected to 75-125 m height, and ash plumes rise to 3-500 m above the crater. [less]
A small ash eruption was reported yesterday at around 09:15 local time. Residents near the volcano heard an explosion sound and some fins ash fell on nearby villages.
Activity has picked up during the past 2 days, as the preceding earthquake swarm had suggested. CENAPRED reports emissions at a rate of 2 per hour. The more vigorous explosions have produced ash plumes of up to 3 km height. The largest was an explosion yesterday just before 17:30 (local time). ...mehr
A large SO2 plume is emitted from the volcano and visible on NOAA satellite data. The alert level remains at "Yellow Phase 2". [less]
Photo of Veniaminof on 13 June, taken from Port Moller by Bob Murphy (via AVO)
The volcano began erupting on Thursday morning, June 13, following several days of increasing seismicity, AVO reported. The official Color Code/Alert Level was raised to ORANGE/WATCH. ...mehr
At least a small lava flow was erupted. A pilot observed an ash plume up to about 12,000 ft above sea level and a lava flow issuing from the intracaldera cinder cone. Residents in Perryville and Port Moller also reported observing the ash emissions at about 11:30 pm AKDT yesterday. Observers located west of the volcano reported that no ash was issuing from the intracaldera cinder cone this morning; however ash emission could resume abruptly at any time. An FAA web camera in Perryville recorded minor steam with possible ash emissions rising from the intracaldera cinder cone on Monday, June 10. Seismic tremor continued to gradually but steadily increase over the next several days. On the morning of Thursday, June 13, intense elevated surface temperatures were recorded in satellite images at the intracaldera cinder cone indicating that an eruption was likely underway. [less]
Veniaminof (Alaska Peninsula, USA): (13 Jun) The Alaska Volcano Observatory raised the volcano alert level from Yellow to Orange. Elevated surface temperatures observed in satellite images this morning at 13:25 UTC (05:25 AKDT) indicate that an eruption at the intracaldera cone is likely underway. ...mehr

Forecasted ash plume from the explosion this morning (VAAC Tokyo)
After 10 days of almost no activity, the volcano has woken up violently with 3 powerful explosions last night (at 22:05 and 23:58 UTC, ash plumes to 10-13,000 ft) and this morning at 04:26. The eruption this morning appears to be one of the largest explosions for a long time, producing an ash plume rising to 16-20,000 ft (5-6 km) altitude. An SO2 plume is also visible on satellite data. ...mehr

El Hierro (Canary Islands, Spain): Seismic activity of the island has been calm over the past weeks. The number of daily small earthquakes continues to be weakly elevated, with hypocenters clustered under the central and western parts of the island. ...mehr
Mauna Loa (Big Island, Hawai'i): The latest update of the USGS mentions that minor inflation of a shallow magma reservoir beneath Mauna Loa may be occurring. Seismicity rates were slightly elevated. However, the level of observed seismicity is far from alarming and the alert level remains at green. No eruption is expected in the near future. [less]
Seismic activity has dropped sharply from 13 events / hour to only one per hour during only 9 hours. No corresponding changes were observed at the surface. The volcano continues to emit a small plume of steam and gas.
A cluster of several (7) volcanic earthquakes up to magnitudes 2.4 has occurred this morning, perhaps heralding some more vigorous activity in he near future. ...mehr
Apart from this, activity has remained stable with about 2 weak steam-gas-sometimes ash-containing explosions per hour. A steam plume often rises about 1 km above the volcano. [less]

The new activity is accompanied by a persistent steam plume and increasing volcanic tremor. So far there seem to be no lava flows or other significant eruptive processes. The new ash emissions are very diluted and reach about 200-300 m height. They were first observed on the Aciation camera of Perryville from last night at around 17-18h local time. AVO who has not yet reported about the ash confirmed to Blog Culture Volcan that the plume indeed contains very small amounts of ash, which pose no problems to aviation (for now). [less]

Shiveluch in Kamchatka had an explosion last night at 21:02 UTC lasting for 6.5 minutes that sent an ash plume to an estimated altitude of about 30,000 ft (7-8 km), KVERT reports. The eruption was not observed directly, but inferred from seismic data. [less]
Activity remains relatively weak. During the past 24 hours, INSIVUMEH observed 6 small explosions with ash plumes up to 500 m height. At the moment, the main risk from Fuego is posed by lahars (mud flows). ...mehr
Following heavy rainfall, unusually strong lahars with fronts of up to 5 meters tall travelled through the Ceniza ravine on 8 June, damaging the road that connects Siquinala to Rochela, San Andrés Osuna, and Ceilán. Deposits of 2-3 meters were left containing blocks of up to 3 meter in size. Geologists who examined the drainages at the feet of the volcano yesterday found recent lahar deposits in the ravines and river valleys of Pantaleon, Ceniza, Las Lajas, Jute, Taniluya and Trinidad.

Current seismic recording from Veniaminof (VNHG station, AVO)
Veniaminof (Alaska Peninsula, USA): Over the past 2 days, AVO has detected gradually increasing seismic tremor beneath Veniaminof and therefore raised the Aviation Color Code to Yellow and the Volcano Alert Level to Advisory. ...mehr
Clear web-camera and satellite views currently show nothing unusual at the volcano. Similar seismic activity has been associated with ash emissions at Veniaminof in the past, most recently in 2005.
As the Indonesian Volcanological Survey (VSI) specified in its latest bulletin, parts of the active lava dome of the volcano have recently (early June) grown higher than the northern crater rim, where it is cut by a valley extending to the northern feet of the stratovolcano. Therefore, potential continued growth of the dome poses the risk of rockfalls and pyroclastic flows reach the northern flanks, where a number of villages are located, namely Pasilulu and Talen. ...mehr
In addition, VSI scientists have detected an increase of seismicity and degassing since early May. This includes volcanic tremor from growing lava dome and deeper earthquakes, possibly related to new magma rising, and the occurrence of notable sulfur smell. Ibu's activity has been characterized by the slow building of a new lava dome inside the breached summit crater since 1999. While present growth rate is still slow, and no or little incandescence is observed at the moment, the new seismic activity could herald a phase of more vigorous activity in the near future. In that scenario, the occurrence of dangerous landslides and pyroclastic flows would be likely and the northern slopes of the volcano should be considered a high risk zone. [less]

Seismic recording from San Cristobal volcano yesterday (CRIN station, INETER)
New eruptions occurred yesterday. The volcano produced a series of 7 small ash emissions between 06:45 to 11:43 am (local time). The explosions were very small and ash plumes only rose up to about 100 m above the crater. ...mehr
The new eruptions were followed by a rise in seismic activity in the form of tremor, which rose to about 3 times normal levels during the afternoon. The tremor pulse was still of relatively low energy and in itself not alarming, as the volcano experiences similar phases of elevated seismicity frequently, but given the recent activity, INETER warns that new explosions, possibly larger in scale, could follow with little warning and that air traffic should avoid the area of the volcano. Unconnected to the new eruptive activity, a small mud flow occurred at 17:10 local time on the lower slopes as a result of heavy rainfall, but did not cause damage. [less]
Seismic recording on 4 June (CNGN station, INETER)
The volcano might be entering a phase of reawakening. A seismic swarm of 49 low magnitude earthquakes and a pulse of volcanic tremor occurred on 4 June, INETER reported in a press release that day. ...mehr
The seismic activity started 08:45 am (local time) on 4 June, increased until 10:30 and the eased again. At the moment, the seismicity is calm again. No further reports have been published by INETER, who has not raised the alert level, but recommended to limit access to the volcano's crater as a precaution measure. Cerro Negro is a popular tourist destination, known for "ash surfing" on the steep ashy slopes. The last eruption of the volcano occurred in 1999. [less]

Etna (Sicily, Italy): During a visit to the summit craters today, we could observe a new hot fumarole in the western pit of the Bocca Nuova, increased bluish degassing from a vent in the saddle between the old and new SE crater and hear deep-seated explosions inside the NE crater. ...mehr
Apart from this, Etna seems to continue its "sleep". Tremor levels have been low during the past weeks, and no eruptive activity has been observed from any of the summit craters since early May. [less]
Stromboli (Eolian Islands, Italy): When observed during 3-6 June, the volcano was at normal levels of activity which had not changed significantly since our last visit 2 weeks ago. On the crater terrace, about 7 active vents were present, with eruptions every about 15-20 minutes: the two vents in the NW crater sometimes erupted simultaneously, one with low ejections of blocks, scoria and ash, the other with loud turbine-like jets of gas and lava fragments that often reached about 250 m height. The hornito at the NW crater rim was not seen erupting. ...mehr
The 3 connected glowing vents in the central crater produced pulsating steam puffs, but no spattering. ... [read more] ... [show less] [less]
Plume from Kikai on Aqua satellite image at 04h05 UTC (NASA, via Blog Culture Volcan)
Tolbachik (Kamchatka): Activity continues with little changes, although the slow trend of decreasing seismic activity persists. A small lava lake 20 m across and weak strombolian activity were recently observed by Russian volcanologists who visited the site. Lava flows continue to be alimented and spread mainly to the SE. ...mehr
Kikai (Ryukyu Islands): New activity seems to have started from Satsuma-Iwo-jima (Kikai) volcano. A steam / gas and possibly ash-containing plume has been observed on satellite images and a thermal anomaly was visible on recent MODIS satellite data. On yesterday morning's NASA Aqua satellite image, the plume from the volcano was about 70 km long to the SW. A thermal anomaly was visible already on images from 23 May. [less]
VSI raised the alert level of the volcano on Flores, famous for its 3 differently colored crater lakes, from 1 to 2 ("normal" to "waspada", "watch") on a scaled of 1 to 4, after one of the 3 crater lakes turned from blue to white on 3 June. In addition, a strong smell of sulfur was noted by people from Pemo village a few kilometers south. ...mehr
The main risk in case of an eruption would be phreatic explosions, ash falls, and the possibly catastrophic draining of the lake(s) potentially causing large lahars and floods threatening nearby communities near and inside the valleys radiating from the volcano. [less]
An small eruption occurred last Sunday (2 June) at 8:43 am (local time), preceded by a rise in seismic activity reported by the local volcano observatory. An ash explosion produced a small rising 300-600 m and light ash fall at Gunung Tujuh about 20 km away. According to local news, the sudden eruption caused panik among inhabitants of Sungai Rumpun village and several evacuated their homes. Some climbers who were on the volcano at the time of the explosions returned unharmed. ...mehr
The eruption was not signalled by VSI nor VAAC and originally only mentioned in some Indonesian media where it is not worth more than a brief note, given the large number of such events every year. Many more eruptions probably occur around the world without getting the attention of international media. Satellite data showed a weak SO2 anomaly at the volcano on 2 June and a thermal anomaly is regularly visible at the often active volcano's summit. [less]
