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 Krakatoa) which vanish due to the 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. The sound explosion 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 bombs that 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 still less than the eruption of Mount Toba and Tambora in Indonesia, Mount Tanpo in New Zealand and Mount Katmal in Alaska. But these mountains erupted deep in the human population is still very little. Meanwhile, when Mount 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 at the time of information technology is growing and growing rapidly.
Noted that the eruption of Mount Krakatau is the first major disaster in the world after the invention of the submarine telegraph. Progress is, unfortunately, has not been matched by progress in the field of geology. The geologist was not even able to give an explanation of the eruption.
The emergence of Mount Krakatau
Rakata Island, which is one of three remaining island Ancient Krakatoa then grow in accordance with the volcanic impulse from deep within the earth, known as Mount Krakatau (or Mount Rakata) made of basaltic rock. Later, two volcano emerged from the crater, named Danan Mountain and Mount Perbuwatan are then fused with Mount Rakata came first. Unity third volcano is called Mount Krakatau.
Mount Krakatoa erupted in 1680 produced andesitic lava acid. Then in 1880, Mount Perbuwatan active issue though is not erupting lava. After that time, there is no volcanic activity at Krakatau until May 20, 1883. On that day, after 200 years of asleep, there was a small explosion at Mount Krakatau. That would be early signs of the massive eruption in the Sunda Strait. Small explosion was followed by small eruptions that peak occurred on 26-27 August 1883.
