Krakatau

Krakatoa

 or Krakatau

Island volcano in the centre of the Sunda Strait, between Java and Sumatra, Indonesia. Its eruption in 1883 was one of the most catastrophic in history. Its explosions were heard in Australia, Ceylon (Sri Lanka), and the Philippines, and large quantities of ash fell over an area of some 300,000 sq mi (800,000 sq km). It caused a tidal wave 120 ft (36 m) high that killed 36,000 people in Java and Sumatra. It erupted again in 1927 and has remained active.

Krakatau 

(also Krakatoa), an island and active volcano in Indonesia, in the Sunda Strait between the islands of Java and Sumatra. Area of the island, 10.5 sq km; altitude, 813 m. It became famous after there was a particularly violent eruption in August 1883, during which about 19 cu km of volcanic ash and other eruption products fell in the adjacent region over an area of more than 800,000 sq km. An increased concentration of ash in the air up to an altitude of 80 km was noted for several years and caused intensive red sunsets. The tidal wave (up to 20 m high) that was triggered by the eruption led to the death of approximately 36,000 people on the neighboring islands. There were subsequent eruptions in 1927–29 and 1950–52.
