Perhaps the most powerful explosion during our 6-days stay was this one at 11:59 local time on 17 Oct, sending a shower of bombs until the forest, the beach and the nearby waters of Anak Krakatau. (Photo: Tom Pfeiffer)
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.
