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…

Krakatau 100 years later , still the ''Classic'' Volcanic Eruption

Nature gave one of its warnings in late May 1883. The uninhabited, largely ignored island of Krakatau, in the middle of the Sunda Straits between the Indonesian islands of Sumatra and Java, suddenly stirred. Billowing clouds of smoke and booming thunder caused a small shiver of terror among the inhabitants of the nearby islands.

Geology of Krakatau Complex

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…

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…

Kondisi Penghidupan Kembali Komplek Gunungapi Krakatau

Tiap letusan gunungapi tipe Plinian merupakan suatu cobaan alamiah yang dapat merubah mukabumi serta kehidupan flora dan fauna secara luas. Ciri letusan tersebut tidak ada bandingannya dengan eksperimen yang pernah dilakukan manusia, demikian diucapkan Ernst (1907), seorang akhli botani Swiss setelah kunjungannya di kepulauan Krakatau tahun 1906 bersama-sama dengan Backer (Bogor), Campbell (Cal…

Pembikinan /Pengukuran Tugu Triangulasi di Sekitar Pulau Anak Krakatau

Sehubungan dengan posisi geografi Pulau Anak Krakatau sampai saat ini belum menentu, sedangkan letak Gunungapi Anak Krakatau dalam penyebaran Gunungapi di Indonesia sangat penting, perlu kiranya untuk menentapkan posisi geografi Pulau tersebut. Dengan demikian Kepala Sub Direktorat Pemetaan Gunungapi menugaskan penulis untuk maksud tersebut yang dibantu oleh Saudara Komar. R. dan Saudara A. R…
