Eruption from the central vent of Stromboli (30 Dec. 2005, photo: Karen B.)
Eruption from the central vent of Stromboli (30 Dec. 2005, photo: Karen B.)

Stromboli continues to be very active. Loud eruption noises are frequently audible all over the island. On a visit by VolcanoDiscovery team members Karen and Tom on the afternoon of 30 Dec. 2005 the following activity was observed:
One active vent in the West crater produced tall, candle-like strombolian eruptions in intervals of 10-15 minutes, throwing incandescent material up to 200-250 m above the crater. 3 vents were active in the central crater, all of them glowing constantly, and relatively strongly spattering; small boiling lava lakes present few meters below the crater rim can be inferred. The northermost of these vents, forming a tall cone, also had strong strombolian eruptions at irregular intervals of 5-25 minutes, throwing lots of very hot, incandescent bombs to up to 100-150m elevation, frequently outside the crater complex. At least one vent was active in the NE crater, which unfortunately was today completely hidden by fumes. It did not erupt visible bombs, but every 10-20 minutes it produced loud hissing noises; we assume that it erupted mainly gas.

Soputan volcano had a small phreatic eruption on 26 December around 12h30 local time, probably caused by heavy rainfall onto the hot lava dome. On 27 December at 0400, a Strombolian eruption began that lasted ~50 minutes. Incandescent volcanic material was ejected ~35 m, and avalanches of volcanic material traveled as far as 750 m E. Around 06h40 the avalanches became larger, as pyroclastic avalanches occurred from the edge of the lava. The avalanches extended 200 m E, and booming noises were heard as far as 5 km from the summit. The Darwin VAAC reported that an ash plume reached a height of ~5.8 km (~19,000 ft) a.s.l. and drifted SE.

Piton de la Fournaise erupted again on 26 December, with a first fissure opening at the base of the summit cone, and a second one just below the slope break of the Grandes Paintes (the steeper slope of the caldera towards the ocean), between 1500 and 1600 m elevation. Lava fountains are emerging from the eruptive fissure and several lava flows are travelling down the slope in direction to the ocean, having reached around 2 km away from the ocean as of Dec. 29.

Popo sends his Christmas greetings with a moderate explosion that produced an ash column of about 2 km height and showering the volcano's top with incandescent fragments early in the morning of Christmas Day (Dec. 25, 2005).

2005 is soon over, and it's a good time to take a break and think about important things in life. The VolcanoDiscovery team wishes you a future without wars and tsunamis. Merry Christmas!

Eruptive activity at Manaro volcano continues, but has decreased significantly over the past week. Scientists are monitoring the eruption, hoping that it will soon be possible to lower the alert level and permit some 3000 residents that had been evacuated to return to their homes.

The eruption at Manaro volcano continues at low levels with mainly phreatic activity. A cone is building up inside the lake forming a small island inside the lake. There are two active vents, one of which ejects water, rocks and mud and the other is producing a tall column of steam and gas (up to 8-10,000 feet). A group of New Zealandean volcanologists has recently visited the volcano and sent the following more detailed reports:

Karthala volcano's second eruption in 2005 ended after 14 days on 8 Dec. 2005 as the Karthala volcano observatory communicated. In its initial phase, the eruption had been driven by phreatomagmatic phase, ejecting large blocks up to 400 m around the crater and producing a lot of ash that cuased severe problems in the south-east and south-west of the island, and particularly in the capital Moroni.

The eruption at Mt. Manaro volcano on Vanuatu's island of Ambae, that had started on 27th of Nov. 2005, is continuing at low or decreasing levels (although drawing a lot of media attention, probably because little other significant volcanic events are occurring at the time). Ash and steam plume rose to a maximum of about 3 km (10,000 ft) height into the air as observed on Thursday 7 Dec. According to the optinion of monitoring volcanologists there are no indications at present that the eruption might escalate.
The eruption is occurring from a vent in the middle of the crater lake Vui — before the eruption known as a picturesque blue lake; this is also the main reason for the intense production of steam.

The third eruption this year, on the 29th of Nov., was one of the shortest one during the past years: lasting only 14hrs, from 6h25 local time, it was already declared ended at 20h15! Because of bad weather conditions, a proper reconnaissance and surveillance of the area has not yet been possible.
