Ausbruch des Krakatau 2007-2010

Nach Ausbrüchen in 1996 und 2001 erwacht Anak Krakatau erwacht Ende Oktober 2007. Um die spektakuläre Aktivität dieses außergewöhnlichen Vulkans zu dokumentieren organisierte VolcanoDiscovery bisher insgesamt 6 Expeditionen zwischen November 2007 und September 2009, bei denen wir mit einer kleinen Gruppe je 3-6 Tage auf der Inselgruppe verbrachten. Weitere Expeditionen sind geplant bzw können auf Anfrage organisiert werden. Schauen Sie für Details auf die Krakatau Special Seite.

Participant and team member Andrej Nikiforov witnessed the ongoing activity in Anak Krakatau's crater lake during the Krakatau Volcano Special tour in Nov 2019. Here some impressions: (Photo: AndreyNikiforov)

Krakatau volcano 19-23 Nov 2018

We managed to arrive at Krakatau at the end of a very intense phase of activity between 17-19 Nov, which produced a new lava flow that reached the sea along a 150 m wide stretch on the southern shore of Anak Krakatau. At the time of our arrival, the effusion rate must have stopped just hours before at most, but the flow front was still active: (Photo: Tom Pfeiffer)

Expedition organizer Galih observed the activity of the volcano during 12-16 Nov. It was characterized by strong ash emissions and occasional vulcanian-type explosions often accompanied by rare volcanic lightning: (Photo: Galih Jati)

At the end of the paroxysm during 17-19 Nov, we spent several hours on the boat in about 700 m straight-line distance from the crater, to observe near-continuous explosive activity in the afternoon and evening of 19 Nov. It ranged from weak fountaining to mild to strong strombolian explosions with or without significant ash emissions: (Photo: Tom Pfeiffer)

Our latest tour to Krakatau during 18-24 Nov rewarded participants with a night filled with fireworks, observed from a paradise beach. What a view! (Photo: Tom Pfeiffer)

The activity observed on 19 Nov continued in a more or less similar way during 20 Nov, although the frequency of explosions had decreased to typically 30 seconds to 1-2 minutes. As the size of explosions observed during the 36 hours we had been on the island group did not exceed a certain threshold (ejecting bombs to the sea), a part of our group decided to take the calculated risk and spend some time on a favorable viewing spot behind the forest and near the shore of Anak Krakatau.
When eruptions eventually started to increase significantly, we left.
Disclaimer: visiting such spots during eruptive phases of Krakatau is very risky and you should be aware that no place on the island of Anak Krakatau is safe from bombs - unexpected large explosions can occur with no warning at any time. (Photo: Tom Pfeiffer)

During 20-21 Nov, activity changes significantly: explosions became more rich in ash and contained much less and much less brighter lava bombs. As well, the intervals between individual events gradually increased overall, reaching up to about 2 hours by 22 Nov afternoon although phases of more frequent activity still occurred.
The most likely cause is that the magma column continued to drop internally and thus favored the formation of a more robust blockage, which in turn favored the occurrence of strong vulcanian-style explosions with less fresh incandescent material, but many fragments of the plug. This process is possibly helped at depth by water seeping into the walls of the conduit (so-called phreatomagmatic activity) as the interior pressure dropped.
Visible activity almost completely ceased during the night 22-23 Nov and picked up only again in the afternoon of 24 Nov, when we saw it from the volcano observatory on our way back. (Photo: Tom Pfeiffer)

Krakatau Vulkan - Ausbruch September - Oktober 2018

Much of the activity of Krakatau we observed could be best described as mild to strong stormbolian activity always rich in ash, occurring at irregular intervals of few minutes to few tens of minutes: (Photo: Tom Pfeiffer)

Our latest group on the Krakatau to Bali tour was lucky enough to catch the latest eruption of Krakatau in its full splendor. We present a small selection of photos taken by expedition leader Galih showing the spectacular strombolian activity from the summit crater.

On 17 Oct, explosions were particularly violent at Anak Krakatau. We show a series of images of a spectacular explosion captured from close range by boat. 2 months later, the cone of Anak Krakatau collapsed into the sea on the evening of 22 Dec 2018, triggering a catastrophic tsunami (more info).
Continued activity that accumulated more and more weight on the cone, built on top of a steep underwater slope in the SW (left in the images), and shaking by explosions like this might well have been the final trigger for that tragic event. (Photo: Tom Pfeiffer)

Along with a small group, Tom Pfeiffer stayed on the island group during a Volcano Special tour from 13-19 Oct: the volcano's activity during this time fluctuated between phases of mild to strong ash venting along with occasional strombolian activity, as well as intermittent powerful vulcanian-type explosions. In this section, some impressions of the violent vulcanian explosions are shown: (Photo: Tom Pfeiffer)

Extensive fumarole fields and large expanses of altered ground are found on the southern and western base of the main cone, especially in the valley between the low, pre-1990 crater rim and the cone. Here are some impressions taken in July during our expedition to Krakatau. (Photo: Tom Pfeiffer)

Anak Krakatau Ausbruch 2007-2008

Auf einem neuen Besuch des Krakatau Anfang Juli konnten wir feststellen, dass die Aktivität immer noch bemerkenswert war. Einzelne ausbrüche fanden allerdings in sehr unregelmäßigen Intervallen von 1-4 Stunden statt. Verglichen mit der Aktivität im November waren die Ausbrüche aschereicher. Einzelne Aschewolken erreichten etwa 1 km Höhe und waren oft von kleinen Entladungsblitzen begleitet. (Photo: Tom Pfeiffer)

Die häufigste Form von Aktivität bestand aus Aschenauswurf in regelmäßigen Abständen von etwa 2 Minuten, die kleine Aschenwolken geringer Höhe produzierten. Die etwas kräftigeren Ausbrüche dagegen ließen oft turbulente dichte Aschewolken auf bis über 1 km Höhe aufsteigen. (Photo: Tom Pfeiffer)
