Krakatoa, or Krakatau (Indonesian: Krakatau), is a volcanic island situated in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The name is also used for the surrounding island group.
On August 26-27, 1883, a small island in the Indian Ocean obliterated itself in one the most notorious volcanic eruptions in history. Krakatau (often spelled Krakatoa) erupted with such violence that two-thirds of the island, about 23 square kilometers, sank into the Sunda Strait. Nearly 40,000 deaths being attributed to the eruption itself and the tsunamis it created. Significant additional effects were also felt around the world. It also remain the loudest noise on human record. The sound was heard across the Indian Ocean, as far away as Rodriguez Island, 4,653 kilometers to the west, and Australia, 3,450 kilometers to the east. The massive eruption also generated a series of tsunamis, which produced waves as high as 30 meters tall.
