Administratively Krakatau belongs to Lampung Province.Krakatau located in Sunda Strait, between Java and Sumatera Island, had been wellknown and recorded in the history since the 16th century.
At that times Sunda strait became a heavy business traffic line from Europe (Holland, England, etc) to East India (Indonesia).
In this modern century Sunda Strait plays more important role as business traffic line as well as the field of geological and maritim research.
Ancient Krakatau was estimated 2,000 meters in height and radius of 9 kms.
Its great eruption happened in pre history in 416 as documented in the ancient Javanese book "Pustaka Raja", and left 3 island as the rest i.e. Rakata, Sertung and Panjang Island.
In the later expanding Rakata comes and followed by Danan and Perbuatan volcanic summits.
The latest great eruption of Krakatau volcano happened on 27th of the August 1883 and destroyed most of its body (3/4 of it). It caused big wave with 40 metres height.
A stemship anchored in Teluk Betung port was thrown 2.5 kms away and washed ashore in the lower course of Kuripan river. It also caused ash and stone hail covered 300.000 squared miles or some 483 sq kms within a radius of 150 kms.
Jakarta (Batavia) and around Sunda Strait such as Anyer, Merak, Labuan, Kalianda, Teluk Betung and Kota Agung became pitch dark.
The eruption was heard from Phillippines, Alice Springs, Rodriquez Island and Madagascar. The power of its eruption was estimated to 21,547.6 atom bomb multiplied.
Besides that, the ash hail produced by the eruption caused obstruction of the view to the sun, so that it created a spectacular view as if the sun was almost gone.
