An active lava dome is growing inside the summit crater of Krakatau volcano.

Our tour expedition leader Andi just returned from a visit and reports that the dome is now about 100 m wide, and has 2 main active vents that eject jets of incandescent gas.

At night, the glow from the dome is clearly visible from Rakata and Sertung islands, and a continuous intense solfatara plume is rising about 500 m above the summit.

Andi and our group observed also that there are now more and larger fumarole fields on the southern part of the cone. According to our observations and the opinion of local scientists, this area is inflated due to the pushing of the lava dome. The seismic recordings from the observatory of Krakatau also show an increase in activity. On 26 March, there were 138 volcanic-tectonic (A-type) earthquakes and 300 long-period (B-type) quakes alone. The question is how long the lava dome remains quiet and purely effusive in style. Explosive, also larger vulcanian-type ones, activity could occur any time.

Isn't that the volcano which caused the 'year without a summer'?

No, that was Tamboro.

There have been larger earthquakes in Java, Northern and Southern Indonesia region in the last couple of days.

Krakatau was almost as huge as Tambora...

And she's gonna blow again!! Cheer

Anak Krakatau Volcano – Small Eruptions – 7th April 2012

On the morning of the 7th April 2012 Anak Krakatau started to produce small eruptions from the southern part of the crater. The eruption clouds only reached a height of 100-150meters and only contained small amounts of ash and only a little rockfall, the eruptions was not of a explosive character. The rest of the crater and its fumaroles are producing a continuous white cloud of steam/gas, rising to greater heights than the eruption clouds from the southern part of the crater. Additionally the southern/southwestern part of the outer part of the crater does now have fumaroles, indicating that magma is trapped under this part of the cone.

Krakatau volcano: new ash venting

It appears that a new vent has opened at the new lava dome of Anak Krakatau volcano and started to emit ash, as Øystein Lund Andersen reports from a recent visit:

"The crater was illuminated by lava (dome) in the night, the location of the light is the southern part of the crater.

On the morning of the 7th April 2012 Anak Krakatau started to produce small eruptions from the southern part of the crater. The location of the eruption was on the same side of the crater, that of the growing lava dome, which several sources have reported about during the last few weeks. This might suggest a collapse of the Lava dome due to the eruptions that now are being seen? The eruption clouds only reached a height of 100-150meters and contained small amounts of ash and only a little rock fall.

The eruptions were not of an explosive character. The rest of the crater and its fumaroles are producing a continuous white cloud of steam/gas, rising to greater heights than the eruption clouds from the southern part of the crater. Additionally the southern/southwestern part of the upper flank does now have fields where steam can be seen rising, these fields did not emit steam during the last visit, an indication that magma is now located under this part of the cone."
