Research Paper On Krakatoa

A century ago, August 26, 1883, the island of Krakatau (Krakatoa) in Indonesia, the volcano exploded with devastating fury. The eruption was one of the most catastrophic natural disasters in history. The effects were experienced on a global scale. Fine ash from the eruption were carried by winds exceeding as far away as New York level. The explosion was heard over 3000 miles away. Volcanic dust exploded in the upper atmosphere, affecting incoming solar radiation and the Earth's climate for several years.

This outbreak led to a series of large tsunami waves, some with a height of almost 40 meters (over 120 feet) above sea level, killing more than 36,000 people in coastal towns and villages along the Straits of Probe islands of Java and Sumatra. Tsunami waves were recorded and observed throughout the Indian Ocean, the
This was formed by the subduction of the Indian plate and the Eurasian plate under Australia.

The Sunda Arc (or Sunda Arc) is a volcanic arc associated with the islands of Sumatra and Java, Sunda Strait and the Lesser Sunda Islands. A chain of volcanoes forms the topographic spine of these islands.

At its peak, Krakatoa reached a height of 790 m (2,600 ft) above sea level. His best known eruption occurred first in 416 AD However, this eruption destroyed the volcano of Krakatoa, which collapsed and formed a caldera 4 miles wide. Verlaten islands and Lang are remnants of this volcano, more then three volcanoes were combined to form the island of Krakatoa.

So Krakatoa was the remnant of the old volcano that had not erupted for some 200 years. Before 1883 the great eruption of Krakatoa, the island of Rakata was made of the three volcanoes and caldera. Given a location of the volcanic cones aligned in north-south direction. The north and south called Poeboewetan was called Rakata. Generally Krakatoa approximate dimensions were 5 9
