Krakatoa (Indonesian name: Krakatau) is an active volcano near the Indonesian island of Rakata in the Sunda Strait. The volcano has erupted repeatedly in known history. The best known of these events occurred in late August 1883.
The 1883 eruption ejected more than six cubic miles (25 cubic kilometers) of rock, ash, and pumice , and made the loudest sound ever recorded by human beings — the sound was heard as far away as Perth in Australia (3,500 km; 2,200 miles), and the island of Rodrigues near Mauritius (4,800 km; 3,000 miles). Many thousands of people were killed and injured by the eruption, mostly in the tsunami (giant wave) which followed the explosion.
The pressure wave from the final explosion was recorded on barographs around the world, which continued to register it up to 5 days after the explosion. The recordings show that the shock wave from the final explosion reverberated around the globe seven times.:9
The eruption destroyed two-thirds of the what was then the island of Krakatoa. New eruptions at the volcano since 1927 have built a new island, called Anak Krakatau (child of Krakatoa).
