Krakatau eruption on 26-27 August 1883 reached volcanic Explosivity Index (VEI) 6 / Colossal. Victims reached 36,417 people (official Dutch records), including all 3 thousand inhabitants sebesi island and about a thousand people on the beach Rather, Lampung, which is seared by the hot cloud Krakatau (Pyroclastic_flow), the rest is indirect, such as the tsunami. The number of victims is already 3 percent of the world population was around 1.25 million.
VEI 6 occurred around once a century, has occurred 11 times since going Christian.

Four times more powerful is the Krakatau eruption of Mount Tambora eruption on 10-11 April 1815 reached a VEI 7 / Super-Colossal. Victims of more than 71 thousand people, including more than 11 thousand inhabitants live by letusannya. The number of victims is already 7 percent of the world population was not 1 million. Impact of climate change on the explosion in such a great year so that the historical record in 1816 as the year without summer.

Thus it can be said that while information technology is growing and developing rapidly. 

Noted that the eruption of Mount Krakatau is the first great disaster in the world after the invention of telegraph under the sea. Progress is, unfortunately, has not been offset by progress in the field of geology. The geologist was not even able to give explanations on the explosion is.
