Krakatau Volcanic Complex located in Sunda Strait, Indonesia, erupted catastrophically in 1883. The eruption was preceeded by the increasing number of seismicity during the last 7 years prior to the eruption. The initial stage of the eruption was indicated by the ash outburst of Perbu- atan volcano in May and followed by another activity in the area south of Danan Volcano in July, 1883. Ashes i…
The Krakatau complex situated in the Sunda Strait, as a part of the Lampung Province (105°21'20" - 105°27'44" E. Long/6°03'0 2, Lot.), consists of four islands: Rakata, Sortung, Panjang and Anak Krakatau. The bordering sides facing each other at Nakata, Sertung and Panjong show a steep morphology which forms the enlders wall, at none places revealing faults. The chronology of the volcanic…

Geochemical and lithological studies of volcanic rocks, decta and pyroclastic flows, those of which were collected from Phenocrystic minerals from the Krakatau Group, were carried out. The volcanic rocks were also investigated by the electron-probe Thermally altered products and related minerals, icroanalyzer. And pyroclastic flow and pumice were examined by X-ray powder iffraction method and t…
