Stromboli volcano erupted today with a new lava flow.(27 Feb. 2006), as we had forecasted in July.Read all
Seismic activity and strombolian activity at Tungurahua has been increasing since the evening of 23 February, 2007. Ash fall has been reported in the villages of Pillate, San Juan, Cotalo and Bilbao. On the evening of 25 Feb. an airline pilot reported observing an ash plume at 6.3 km altitude.Read all
During aerial observations on 20 February, ash deposits were seen on the W sector of a summit glacier and dispersed to the NW. Fumarolic plumes originating from several points along a fissure rose to 7 km (23,000 ft) a.s.l. Small mudflows from a glacier traveled down a gorge. Based on news reports, small avalanches prompted officials to order evacuations from towns bordering rivers.Read all
During our latest expedition to the active crater of Lengai volcano from early 31 Jan - 2 February 2007, no eruption of natrocarbonatite lava occured from the summit vents. According to local Maassai guides, the central area of the crater with the large collapse pit near the tall hornito T49b had not seen significant changes since last summer.
From an open vent in the NE corner at the bottom of the pit at the base of the hornito, loud washing-machine like sounds of boiling lava was audible all the time. A large pool of lava must be found somewhere at very shallow depths in some caverns beneath that area. This assumption is confirmed by the glow of lava that was clearly visible one night from a second, smaller vent located about 30 m south of the large vent in the base of the collapse pit. One guide confirmed he had seen spattering of lava from this vent some two weeks earlier.
The first eruption of Piton de la Fournaise volcano on Feb. 18 lasted only 9 hours, making it one of the shortest in its recorded history (following one of its longest ones as well...).
The observatory reports that the strong inflation of the summit area persists, suggesting that activity could resume anytime in the near future.
INGEOMINAS and local newspapers report the awakening of Nevado del Huila volcano, a massive stratovolcano with an ice cap that has been dormant for 400 years.Read all
Piton de la Fournaise volcano started to erupt yesterday (18 Feb.07) at 16h38 local time. The eruption occurs along a fracture cutting Dolomieu crater in E-W direction and extending until the outer rim at 2400 m elevation, where 3 weekly alimented lava flows were observed. The main activity takes place inside the crater where low lava fountains emit large quantities of lava that have already covered about one third of the shallow crater floor.
This eruption is Fournaise's first one in 2007 and comes just about 6 weeks after its last eruption. The activity had been preceded by increased seismicity over the past days and intense tremor started just about 25 minutes before the onset, marking the final phase of fracturing of the ground by the rising magma.
Kamchatka's Klyuchevskoi volcano started erupting Thursday Feb. 16. KVERT reports increased seismicity and visible strong strombolian / vulcanian activity, producing jets of incandescent material to 300 m above the crater and ash plumes to an altitude of 5-6 km.
The lava dome at Mount St. Helens continues to grow slowly, accompanied by low-level seismicity.Read all
INSIVUMEH reported that explosions from Fuego produced white and gray plumes that rose to an altitude of 4 km (13,000 ft) a.s.l. and drifted SW on 12 January. Incandescent material was propelled up to 75 m above the summit and incandescent blocks rolled W towards the Taniluyá and Santa Teresa ravines on 12 January and S towards the Ceniza ravine on 12 and 16 January. Based on information from the Tegucigalpa MWO and satellite imagery, the Washington VAAC reported that a faint plume was seen on 12 January drifting W.Read all
Over the past days, lava-dome growth at Soufrière Hills continued and was focused on the NW sector of the dome. Occasional pyroclastic flows travelled down to the W in Gages Valley, to the NW in Tyres Ghaut and S down the Tar River Valley.Read all
Sangay volcano remains in activity as satellite observations by the VAAC Washington reveal, warning about ash plumes of 800 m above the volcano. A thermal anomaly is also visible in the crater.
Karymski stratovolcano continues to be very active. Frequent explosions produce ash plumes of 2-3 km height, probably accompanied by pyroclastic flows. Explosion-type earthquakes range from 100-350 events per day. Direct visual observations are difficult or impossible due to bad weather.Read all
A new eruption started at Karthala volcano (the 4th within two years). Details of the eruption are still scarse, but observations from the capital Moroni (15 km distant) suggest that the activity might not take place in the Chungu Chahale crater, where the other recent eruptions were located, but north of it or perhaps even outside the caldera.
Residents of Moroni report seing "jets of red flames above the summit of Karthala" in the night of 12-13 January. On 13 January, eruptive tremor was low but a number of earthquakes could be felt in Moroni and an ash plume was observed above the volcano.
Telica stratovolcano had a weak phreatic eruption on 9 January starting at around 15h00 local time, following seismic precursors starting from around 07h00. Explosions from the central crater ejected gas and ash to 500 m elevation.Read all
As our correspondand Roy reports, a major explosion (probably a major dome collapse) has just occured on Montserrat's volcano, producing an eruption column of 30,000 ft (10 km).Read all
Soufrière Hills volcano continues to be in a high eruption state. Frequent rock falls trigger pyroclastic flows from the lava dome towards the NW sector Tyres Ghaut and Gages Valley. The run out distances in Tyres Ghaut have, however, shown signs of increasing, possibly exceeding the previous maximum estimate of 1500 m.Read all
Based on pilot reports, the Buenos Aires VAAC reported continuous emissions from Ubinas on 27 and 30 December. Ash plumes rose to 4.9-8.5 km (16,000-28,000 ft) a.s.l. and drifted E.
Santa Maria volcano is in a heightened state of activity. On 28 Dec. 2006, INSIVUMEH reported a series of small sector collapses from the SW edge of Santa María's Caliente dome that produced pyroclastic flows travelling ca. 2 km down a ravine.
On 29 December, another collapse produced pyroclastic flows and incandescent blocks. Thick ash plumes associated with the pyroclastic flows on both days reached an altitude of 4.3 km (14,000 ft) a.s.l. and drifted W and NW.
Washington VAAC reported minor emissions of gas and possible ash visible on satellite imagery on 1 and 2 January.
After its violent eruption on 24 December, on aerial observations reported by KVERT show that part of Bezymianny's lava dome was destroyed during that activity. The level of Concern Color Code was lowered to Yellow.
Since the end of the lava emission on 15 December 2006, Etna continues to be rather quiet. INGV reports the presence of ash emitted from SE crater during the night of 25-26 December.
Over the past weeks, the lava dome of Montserrat's has been growing at rapid pace. The possibility of major dome collapse events (such as on May, 20, 2006) and associated pyroclastic flows promted the government to evacuate hundreds of people living at the base of the Belham Valley. Montserrat's Soufriere Hills volcano.Read all
One of the longest eruptions of Piton de la Fournaise during the past decades ended after 4 months on January 1st 2007.
