Worldwide Volcano News and Updates
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.Read all
