 Panorama of the summit crater of Anak Krakatau (2 July 2012)  The collapse pits at the site of the 2012 lava dome in the western part of the summit crater of Krakatau (2 July 2012)  One of the new areas with shallow submarine hydrothermal activity on the western shore of Anak Krakatau, causing an intense orange water stain (2 July 2012) Seismic activity when visiting the local volcano observatory was at very low levels, suggesting that Anak Krakatau is at the moment in a phase of repose. Interestingly, a number (at least 4) areas with apparent submarine hydrothermal iron-bearing vents were observed that had not been there last year. In these areas, bubbling could be seen in the water, and where accessible, iron-rich greenish warm mud was found at the sea floor, which oxidized to orange when brought to the surface. The sea water around these areas had an intense yellow stain. Very similar submarine activity is known from around Nea Kameni island, Santorini.
