Not to be confused with Krakatoa

Volcanic island in the Sunda Strait between Java and Sumatra in Indonesia

Anak Krakatoa (English: "Child of Krakatoa") is an island in a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung.[1] On December 29, 1927, Anak Krakatoa emerged from the caldera formed in 1883 by the explosive volcanic eruption that destroyed the island of Krakatoa.[2] There has been sporadic eruptive activity at the site since the late 20th century,[3] culminating with a large underwater collapse of the volcano which caused a deadly tsunami in December 2018, followed by subsequent activity in 2019 and an eruption in April 2020. Due to its young age, the island is one of several in the area which are of considerable interest to volcanologists, and the subject of extensive study.

Volcanic activity at Anak Krakatau, 2008

2010: The thick brown plume of ash, steam and volcanic gas rising from Anak Krakatoa in this true-colour satellite image is a common sight at the stratovolcano.

Until its 2018 collapse, Anak Krakatau had grown at 13 cm (5.1 in) per week on average since the 1950s. This equates to an average growth of 6.8 m (22 ft) per year. Its most recent eruptive episode began in 1994. Quiet periods of a few days have alternated with almost continuous Strombolian eruptions since then. Hot gases, rocks, and lava were released in an eruption in April 2008. Scientists monitoring the volcano warned people to stay out of a 3 km (1.9 mi) zone around the island.[4] On 6 May 2009, the Volcanological Survey of Indonesia raised the eruption alert…
