Krakatoa is a volcanic island that is still active and located in the Sunda Strait between Java and Sumatra. This name was never pinned on a volcanic peak there (Mount Krakatau) which vanish because of eruptions themselves on 26-27 August 1883. The eruption was so powerful; hot clouds and the resulting tsunami killed about 36,000 people. Until before the date of December 26, 2004, this is a terdahsyat tsunami in the Indian Ocean region. Explosion sound was heard up in Alice Springs, Australia and the island of Rodrigues near Africa, 4653 miles. Yield is estimated at 30,000 times the atomic bomb that was detonated on Hiroshima and Nagasaki at the end of World War II.
The eruption of Krakatoa caused global climate change. The world was dark for two and a half days due to volcanic ash that covered the atmosphere. The sun shines dim until next year. Scattering dust visible in the sky Norway to New York.
The explosion of Krakatoa is actually less than the eruption of Mount Toba and Tambora in Indonesia, Mount Tanpo in New Zealand and Mount Katmal in Alaska. However, the erupting mountains far in the human population is still very little. Meanwhile, when Krakatoa erupted, the human population is dense enough, science and technology has evolved, the telegraph was invented, and submarine cable has been installed. Thus it can be said that while information technology is growing and growing rapidly.
