Anak Krakatau Island, Volcanic island in South Lampung, Indonesia
Anak Krakatau Island is a volcanic formation in the Sunda Strait between Java and Sumatra, where an active cone emits steam and ash throughout the year. The crater sits above sea level, showing signs of ongoing volcanic activity that reshapes its surface over time.
The land surfaced from the ocean in late 1927, forming at the site where the original volcano disappeared in 1883 during one of the most violent eruptions in recorded history. The young island continues to grow, adding material through repeated eruptions, though a collapse in 2018 removed a substantial portion.
Indonesian scientists monitor the volcanic activity through a network of observation stations, contributing to global understanding of volcanic formation processes.
Access requires official permits from Indonesian authorities and boat transport from designated ports in Lampung or Banten provinces. Visitors should be aware of hazards, as eruptions can occur without warning and safety depends on daily conditions.
The volcanic cone grows roughly five meters per year through continuous eruptions that regularly add rock and ash. The island remains almost entirely uninhabited, with only occasional scientific teams documenting its development.
