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, Japan, and the Philippines, and large quantities of ash fell over an area of 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 is still active.
