Anak Krakatoa
island in South Lampung Regency, Lampung Province, Indonesia
Anak Krakatoa, or Anak Krakatau (Indonesian for 'child of Krakatoa'), is a volcanic island and an active volcano in Indonesia. On 29 December 1927, Anak Krakatoa first emerged from the caldera formed by the explosive volcanic 1883 eruption of Krakatoa that destroyed the island of Krakatoa (Krakatau). Sporadic eruptive activity has occurred at the site since the late 20th century. A large sector collapse of the volcano occurred on 22 December 2018, causing a deadly tsunami—the 2018 Sunda Strait tsunami. There has been subsequent activity since then in the 2020s. Anak Krakatoa's 4–6 September 2026 eruption caused a fog of ash in the nearby islands of Java, Sumatra, and other surrounding areas. Owing to its young age, the island of Anak Krakatoa is one of several in the area which are of interest to, and the subject of extensive study by, volcanologists.
History
Background
After the cataclysmic eruption of Krakatoa in 1883, Krakatoa Island lost approximately two-thirds of its mass on the northwest side, obliterating the peaks of Perboewatan and Danan, and leaving only the southern half of the island, including the Rakata Volcano, as the last remnant of the original island. The lost area became a shallow sea.
Regrowth
In early 1927, visible volcanic activity began to occur at the point located between where the former peaks of Mount Perboewatan and Mount Danan had been.
This brief starts where responsible research should: with the source description of “Anak Krakatoa” as island in South Lampung Regency, Lampung Province, Indonesia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as island in South Lampung Regency, Lampung Province, Indonesia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q2205302. Authority coordinates are -6.098, 105.426. 1 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1927, 1883, 2018 and 2026.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
