Pulau Anak Krakatau

Krakatau

Kaldera · Indonesia · 285 m

Krakatau volcano lies in the Sunda Strait between Sumatra and Java. The historic eruption of 1883 destroyed much of Krakatau Island, forming a submarine caldera and producing detonations that were heard as far away as Australia, and numerous smaller eruptions have occurred since. Rakata Island in the background is the truncated rim of the 1883 caldera. Anak Krakatau in the foreground is a post-caldera cone that first breached the surface of the sea in 1928 and has been in frequent activity since then. The black lava flow at the right side of the photo was erupted in 1975.

Ringkasan geologi

The renowned Krakatau (frequently misnamed as Krakatoa) volcano lies in the Sunda Strait between Java and Sumatra. Collapse of an older edifice, perhaps in 416 or 535 CE, formed a 7-km-wide caldera. Remnants of that volcano are preserved in Verlaten and Lang Islands; subsequently the Rakata, Danan, and Perbuwatan cones were formed, coalescing to create the pre-1883 Krakatau Island. Caldera collapse during the catastrophic 1883 eruption destroyed Danan and Perbuwatan, and left only a remnant of Rakata. This eruption caused more than 36,000 fatalities, most as a result of tsunamis that swept the adjacent coastlines of Sumatra and Java. Pyroclastic surges traveled 40 km across the Sunda Strait and reached the Sumatra coast. After a quiescence of less than a half century, the post-collapse cone of Anak Krakatau (Child of Krakatau) was constructed within the 1883 caldera at a point between the former Danan and Perbuwatan cones. Anak Krakatau has been the site of frequent eruptions since 1927.
