Krakatau volcano (Indonesia) Nov 2018 eruption: a magic night on the island

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.
