With the visit in June 2009 a considerable smoke trail was to be seen. The excursion of this year was blessed by a meager dim light over the Anak summit. From the island fragment Sertung, one of the remnants of the 1893 eruption lain northwest you had a outstanding screen window of the Anak crater together with the island Rakarta. However we also discovered the momentarily longest faces of the Krakatoa archipelago on Sertung.

Now something oomph had to amplify the whole thing.

What was the reason  of the weak red light in the crater region. May some weak strombolian activity, or a lava lake? Grumble, grumble…, also a risky decision, because a mounting of the Anak summit cannot be classified as straight harmless. Thus Chris Weber had the exiting experience in the recent past, that the volcano started an ash activity while standing at the rim. Luckily the activity did not develop itself further stronger and restrained fast again. Also spontaneous explosive activities can occur during the stay time at the edge of crater. In this case you would have hardly a chance to survive such a volcano attack.

Attending ourselves to the curious monitor lizards the decision laid in a far distance during the whole morning time. But with the landing on Anak Island the ascent was clearly decided. Our main reason was if you already find no activity, you should take the rare opportunity to risk a view into the vent.

The ascent on that for instance 400m high cinder cone began from northeast, and emerged itself as extremely difficult. Even experienced mountain climbers will feel the true joy in this loosen rubble field and will fight against constant flight and roll ambition. The three steps ahead and two step back method turned out after one hour as successful, and with tension the view was expected.

Arriving on the edge of crater we got real astonished. On the opposite of the crater side a typical lava plug with innumerably small gas flames could be observed on the base. Like cemented with bitumen this plug was fixed, and everyone had really the feeling, this cork wanted ‘out’ from its anchorage at anytime.

Would the gas couldn’t have escaped by the tears the positive pressure and/or an explosion would have beaten the plug already far up. In a better way you cannot represent the positive pressure principle at the volcano. We would not have been averse against an exemplary demonstration, but the circumstance of this explosive situation pushed us down again after one hour. The descent despite darkness can be judged at the south side as substantially simpler.

Somewhat dusty but really happy leaving the danger zone without bigger demolitions, we engaged ourselves again with the mangy kitchen monitor lizard (up to 2.5 meters) and the deliciously prepared sea food dishes by our cooks, incl. Bintang
