Krakatoa volcano eruption Oct 2018: dangerous vulcanian explosion from close

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.

On 22 Dec 2018, continued eruptions of Anak Krakatau had accumulated too much weight on the cone, which is built on top of a steep underwater slope. This made it prone to landslides and explosions like this one could have triggered it to give way. (Photo: Tom Pfeiffer)

Eruption video

Participant on our Krakatau Volcano Special tour managed to capture this extraordinary explosion, which involved a small lateral blast, by video. The video has gone viral since it was first published. It shows a place that now no longer exists: two months later, the cone collapsed into the sea and caused a deadly tsunami that hit Java's west coast. An event like this might well have been a final trigger for this to happen.
