Krakatoa (/ ˌ k r ɑː k ə ˈ t oʊ ə, ˌ k r æ k-/), also transcribed Krakatau (/-ˈ t aʊ /), is a caldera [1] in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa archipelago) comprising four islands.
Lithograph of the eruption c. 1888. The 1883 eruption of Krakatoa (Indonesian: Letusan Krakatau 1883) in the Sunda Strait occurred from 20 May until 21 October 1883, peaking in the late morning of 27 August when over 70% of the island of Krakatoa and its surrounding archipelago were destroyed as it collapsed into a caldera.
A new parasitic cone, called Anak Krakatau (or the child of Krakatau), rose from the sea at the centre of the caldera in 1930. [14] The other Krakatau islets from the 1883 eruptions are known as Sertung, Panjang and Rakata. Java is a relatively small island compared to Sumatra, but it has a higher concentration of active volcanoes.
Mount Krakatau is a volcanic caldera located in the Sunda Strait, close to the Lampung province. The Krakatoa erupted from 20 May until 21 October 1883, which caused landslides, producing high waves in the coastal area of Lampung. [23] [24] Between 1969 and 1970, the total area of forest land in Lampung that had been used was 249,200 hectares.
Krakatoa is an active stratovolcano located in Indonesia, and lying on the far western rim of the Pacific Ring of Fire.Krakatoa is a notably powerful volcano, with the 1883 eruption being one of the deadliest and most destructive volcanic events in all of recorded history.
Mount Emmons, Mount Hague, and Double Crater are post-caldera cones. [6] The topography of the Basin and Range Province is a result of crustal extension within this part of the North American Plate (rifting of the North American craton or Laurentia from Western North America; e.g. Gulf of California, Rio Grande rift, Oregon-Idaho graben).
Anak Krakatoa, c. 1929. In early 1927 volcanic activity began to appear at the point located between where the former peaks of Mount Perboewatan and Mount Danan had been. [2] This was a short-lived appearance of a small island that was sunk by sea waves within a week. [3]
