Krakatau :: essays research papers

KrakatauKrakatau (Krakatoa), is said to have created the worst volcanic fires in history, in 1883. Ancient Krakatoa formed in 416 A.D. and nevertheless exists today in Indonesia. That same explosion, in 1883, created 130 feet tsunamis, which destroyed 130 soaringal homes, two docks (India and Australia), and killed about 36,000 people. It created very loud sounds and was heard as far away as Madasagascar, about 3,000 miles away from Java, where Krakatau was. Some people even believe that it may have been the reason for the drop in temperature and the spectacular sunsets for the following(a) three years.Krakatoa has erupted many times in its lifetime, but this paper will only share about 3 eruptions 1883, 1988, and 1992. In 1883, Krakatoa had its most dicey explosion on August 27th. It blew itself to bits, literally It destroyed 75% of itself along with many other people living near the coastlines of Australia and India. In 1988, Krakatoa erupted in February, hence continued on March 16th on which was reported caused two little(a) lava flows from its new crater, then continued into April, causing frequent explosions to eject small plumes of fire. The last eruption well talk about was in 1992. This explosions strongest activity point occurred on November 12, when Krakatoa started shooting lava-bombs out of its crater onto the north coast and some lava flowed into the sea.While we know volcanoes erupt, how do they erupt? After some research, I found that they are caused by gas pressuring the molten magma, forcing the magma to push upwards into the weak zones in the Earths crust. Thus, this allows the magma to push its way out through the volcanos vents to be erupted from its crater to become lava. In the 1883 eruption, the eruption lasted from August 23-27. In 1988, the explosions lasted from February to April, erupting continuously. And in 1992, it lasted from November 7, 1992 to August 14, 1993, one of Krakatoas longest eruptions. In 1992, the lava flow ed one kilometer to the north, moving the shore 100 meters more northerly than the former shoreKrakatoa has caused much damage to the world, but what specifically has it done?
