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.
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…
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…

I came up to Tokyo by flight on January 18th (and returned to Kagoshima on 20 th) to talk with staffs of the JSPS ( Japan Society for the Promorion of Science). We talked about the successful Krakatau Volcano Research and its related works which were made jointly together with Indonesian excellent co - workers.
Setelah mengetahui tentang kedasyatan letusan Krakatau dalam tahun 1883 dan akibat - akibat yang ditimbulkannya secara agak mendetil, sampailah kita sekarang ke sebab - sebab terjadinya letusan gunung berapi itu.
Sesuai rencana kerja proyek pemetaan geologi Gunungapi Sub-Direktorat Pemetaan Gunungapi Direktorat Vulkanologi pada PELITA III geologi gunungapi Krakatau. Pekerjaan lapangan berlangsung 40 hari dari 13 Maret sampai dengan 21 April 1982.
From the respeots of volcanostratigraphy, geology and petrography, major efforts were payed for field inspection of lavas, pyroclastics and pyroclastio flow deposit and for sampling for petrological and geochemical laboratory works.
