The activity of Anak Krakatau continues with no sign of weakening. As observed during a recent expedition from 4-8 June, strong strombolian activity from the new vent between the old summit vent and the 2007 vent on the S side of the summit cone has filled the collapse crater from 2007 and throws incandescent blocks and bombs to up to 500-700 m above the vent and reaching severl hundreds meters distance. At times, this activity is similar to small lava fountains and at other times, eruptions are more vulcanian-type, rich in ash, producing plumes up to 1 km high. The latter are often accompanied by loud blasts that can be heared many kilometers away and give impressive echoes on the walls of the surrounding caldera. Indivudal explosions are following each other at invervals of 2-5 and rarely more minutes. Photos of this activity can be found here. ...

The activity of Anak Krakatau is increasing. Direct observations of the crater in late April revealed strong strombolian activity from a vent inside the crater of the 2007-2008 eruption building up a new scoria cone inside this crater. We are planning to revisit the volcano in the first week of June for more observations.
