Krakatau volcano (Indonesia) eruption update: decline in activity reported, new lava flows
Tuesday Sep 04, 2012 09:02 AM | BY: T
Ash emissions, explosive activity from the summit and steaming from probably what is a new lava flow at the SW shore next to the forest (photo: 3 Sep).

An close up on what was described as "geothermal area", but looks like a lava flow entering the sea (3 Sep)is, on the 2th September, my sources say.
According to unconfirmed news the eruption started declining since 22:00 pm last night (3 Sep).

In the meanwhile, our friend Oystein who had been on the island during one of our 2-days special trips published a few photos that suggest either that one or 2 vents have opened on the SW and NW shores (in the areas where we observed new hydrothermal vents in early July), or, more likely one or two lava flow(s) are reaching the sea there and create heavy steaming.
If you like to join us on a special last-minute expedition next weekend/early next week 9-14 Sep, please look at the Krakatau Special page and get in touch with us!

During our recent expedition to Krakatau volcano, we could no longer see the lava dome active during Feb-May this year. Probably, the magma column had dropped in mid to late May and the dome collapsed. At its place, there were only 2 collapse pits, very hot ground and intense degassing from numerous fumaroles inside and outside of the now large summit crater. ... [more]
