Krakatoa eruption 1883

 
Krakatau was the name of this mountain, maybe everyone especially the Indonesian people to know that the volcano is still active. Krakatau is still active volcanic island located in the Sunda Strait between Java and Sumatra islands. This mountain has erupted on 26-27 August 1883 with a very intense explosion. Hot clouds and resulting tsunami killed an estimated 36 000 people eruptions. Tsunamis generated by eruptions is terdasyat tsunami that ever happened in the Indian Ocean. Eruptive sound audible to the Alice Spings, Australia and Africa Rodirgues island. 30 000-fold yield atomic bombs dropped on two Japanese cities Hiroshima and Nagasaki in World War II nd.
Eruptions affect global climate at that time. World a dark time for two days due to volcanic ash that covered the atmosphere. The sun was shining dim until next year. Scattering dust to be seen in the sky Norway and New York.

Actually, the eruption of Krakatoa is still small compared with the eruption of Mount Toba and Tambora in Indonesia, Mount tanpo in New Zealand and Katmal in Alaska. But the volcano erupted when the human population is still small. As with the tragedies that the eruption of Krakatoa occurred in the human population is dense and the progress of science has been growing rapidly, the telegraph was invented and submarine cable has been installed. So at that time information has been growing rapidly.

Krakatoa eruption, including the biggest disaster at the time of advanced technology, but unfortunately the progress that have not compensated by the progress of geological science, geology so that scientists can not explain these eruptions.

Starting in 1927 or approximately 40 years after the eruption of Krakatoa, a volcano which emerged called Anak Krakatau. Anak Krakatoa is increasingly high and active. Anak Krakatau predicted the growth rate increase of 20 inches per month. So every year Anak Krakatau will rise 20 feet and 40 feet wide. If counted, then within 25 years the addition of high-achieving child of Krakatau 7500 inches or 500 feet higher than the previous 25 years. The cause of the high mountains due to the material that comes out of the new belly of the mountain. Currently the height of Anak Krakatau reach about 230 meters above sea level, while Mount Krakatoa previously had 813 meters high above sea level.
