Krakatau, West of Java
I. Introduction
Krakatau is a former stratovolcano that is located within the Sunda Strait between Java and Sumatra. The most popular and logical theory for the origin of its name is that it was adapted from the sanskrit word “Karkata”, justification being that Rakata is cited as meaning crab in the older Javanese language (Wilson, 1999). The origin of this volcano is perhaps first noted in the Javanese Book of Kings in 416 A.D. as a “thundering sound” in Kapi, a westward province of Java. Despite this reference, no geologic evidence of an eruption has been reported of that time. It is believed that during this time period the eruption left the three islands that we know of today.

By 1930 it crested anew producing flows faster than the waves could erode them. It currently grows at approximately 6.8 meters per year and is active, alternating between quiet periods and strombolian eruptions (Shoeman). It is located between the two former volcanoes Danan and Perbuwatan
X. Anak Krakatau’s Eruptions
In terms of chemical composition, it has been noticed that the flows of Anak Krakatau are similar to those in Hawaii. There is a presence of basalt as well as the old rhyolite of Krakatau, making Anak Krakatau a chemically complex volcano (Shoemaker). As denoted in the geochemical section of this paper, Anak Krakatau is next in a series of magma types, or is slightly differentiated, and is a significantly active volcano with enumerative degassing events. Eruptions include frequent pyroclastic flows
XI. Conclusions
Overall, Krakatau was one of the most infamous and devastating volcanic eruptions mankind has been around to witness. Ranking a VEI of 6 and a death toll of over 36,000 people, the impacts of this hydrovolcanic eruption were astounding. In light of this, more information was recorded and spread than with any preceding
