The principal activity observed in June was small to medium-sized strombolian activity, with frequent explosions from the new crater at intervals of 2-5 minutes, throwing incandescent blocks to several hundreds of meters height. (Photo: Tom Pfeiffer)

After a 36 hrs pause in activity between the evening of 30 June and the morning of 2 July, Anak Krakatau started again with powerful vulcanian explosions. The largest of these explosions were preceded by an inflation and shaking of the active cone or lava dome, triggering rock-slides from its flanks, until the plug gave way in giant explosions ejecting a rapdly expanding mass of red-hot lava, solid rocks, and large amounts of ash, forming plumes of up to 2 km heights.

A VolcanoDiscovery expedition spent 4 nights on Krakatau from 4-8 June and observed strong strombolian activity, often accompanied by loud blasts, from a new vent located between the old summit crater and the 2007 crater. This activity has essentially filled the 2007 crater with a new cinder cone and 'healed' the 2007 scar. At the time of leaving the island yesterday, activity was still going strong. Here are some first impressions from the tour as observed between 4-8 June 2009: (Photo: Tom Pfeiffer)

Hundreds of explosions have left their mark on Anak Krakatau. The slopes of the old crater and the upper forest area are dotted with impacts. The seismological sation and many trees have been destroyed. (Photo: Tom Pfeiffer)

We decided to revisit Anak Krakatau in early July. Its activity of Anak Krakatau was still moderately strong, although individual explosions only occurred at intervals between 1-4 hrs. Generally, eruptions were more ash-rich than in November, these eruptions were rich in ash, with frequent small lightnings in the ash plumes that reached up to about 1 km height. (c)

The most frequent type of activity was ash venting, occuring at intervals of typically 2 minutes, but the resulting plumes were relatively low ash clouds. Some of the more powerful explosions produced tall plumes of over 1 km height. (c)

Most of the material ejected during its ongoing eruption is ash and blocks from the crater and conduit walls. Incandescent material (i.e. fresh magma) was first observed at Bromo in Dec 2010. Mild strombolian activity was visible at night during our tour from 15-19 Feb, usually accomanied by hissing and soft explosion sounds. At least two different vents were active inside Bromo's crater. Most of the strombolian activity took place from the vent in the W half (right in the pictures) of the crater, while a vent in the eastern half (left) was the principal site of ash emissions and occasional powerful explosions accompanied by loud detonations and shock waves rattling windows in up to several kilometer distance.

Bromo's eruption is characterized by strong, near continuous ash emission. The photos here were taken between 15 and 19 February. At times, the emissions were accompanied by constant noises resembling ocean surf, interrupted by powerful shock-wave producing blasts reminding of cannon fire. In between, phases of silent emission of huge, billowing ash clouds occured as well. Ash emission was decreasing from 17 Feb on, and became only intermittent. At the same time, strombolian activity in the crater with at night visible incandescence seemed to increase. (Photo: Tom Pfeiffer)

Ngadirejo village in the district of Probolinggo, East Java, lies close to the Tengger caldera. It is one of the areas that suffered most from ash fall during Bromo's recent eruption. Up to 30 cm of dense, black ash have accumulated in the area, on fields, roads and houses, burying literally everything.
The thick blanket of ash has killed almost all vegetation, destroyed crops, and damaged houses, power lines and water supply. The area has been declared disaster zone by Indonesian authorities. Despite this, only few people have actually left their houses. People in the village are optimistic and determined to resist the ongoing crisis and carry on with their lives as well as possible.
