Krakatoa is a volcanic island that is still active and is located in the Sunda Strait between Java and Sumatra. This name was ever pinned on a volcanic peak over there because of the eruption on 26-27 August 1883,
 The eruption was so powerful; hot clouds and the resulting tsunami killed about 36,000 people. Up until December 26, 2004, this is the most powerful tsunami in the Indian Ocean region. Cracking noise was heard up in Alice Springs, Australia and the island of Rodrigues near Africa, 4,653 kilometers. Yield is estimated at 30,000 times the atomic bomb that was detonated on Hiroshima and Nagasaki at the end of World War II.

In 1929, this small island disappeared again but then resurfaced along with eruptions in 1930, and after the great eruption in February 1933 emerged with a larger size. In 1935, the island is almost circular shape, with a diameter of about 1200 m, a height of 63 m and in 1940 height of 125 m. In 1955 the island is increasing its height to 155 m above sea level. In 1959 the island is bursting back and thick black smoke to a height of 600 m.

Along with volcanic activity volcano on this island, the highest point of the island is growing at a rate of 7-9 meters per year.
