Damas Heren. In dese maand augustus herdenken wij het feit, dat de krakatau vulkaan honderd jaar geleden so'n geweldige uitbarsting heeft genas d das ay over de gahale serald bekend en opgemerkt is geworden. Krakatau.(6.2).
Dalam Agustus ini kita memperingati kenyataan bahwa gunungapi Krakatau seratus tahun yanh lalu telah mengalami letusan begitu dasyat hingga ia diketahui dan menarik perhatian seluruh dunia.
The significant change in seismic activity for an active volcano is closely related to the stage of volcanic activity. Even in the dormancy period, the observation of seicmic activity of a particular volcano is very important to evaluate the status and to anticipate the future behavior. The Volcanological Survey of Indonesia installed triparti- te instruments at the Anak Krakatau and Sertung…
Volcanology is ained at the scientific study of phonomona, which strictly speaking, only refers to manifestations of surface cruptions of molton rock or magna and their related gasos, with the structuros, deposits, and other offects produced thoroby. Until now physiographio descriptions of the Indonesian volcanoos, their eruptions and or porio- dic increased activities, the geomorphological lan…
The activities and magmatic cycles of the Krakatau Volcanic Complex are closely related to the goology and tectonic position of Strait Sunda, which are more related to Sumatra than to Java. The basoment of Strait Sunda consists of ignimbrites and acid tuffs of 0.1 million year old, and the thormal gradient in and around Sunda Strait is about 6.7°C por 100 meter. Tectonically, strait Sundo is a…
Present situation of the Sumatra Island seems to indicate the clockwise rotation of about 40 degrees for Jawa (Fig.1). Ninkovich (1970) proposed a hypothesis that in the Late Cenozoic Sumatra rotated clockwise about 20 degrees and formed the present configuration. Moreover, Sasajima et al (1980) said that after the Triassic until the Early Tertiary, Sumatra should have rotated clockwise by 62.4…
Various discussions have been made by many authors as respects the eruption mechanism of Krakatau caldera (e.g. Williams, 1941; Yokoyama, 1981; Self and Rampino, 1982; Yokoyama, 1982). Accumulation of geophysical data may provide important information to clarify the problem. Yokoyama and Hadikusumo (1969) have already established the gravity stations Krakatau Islands. The low residual anomalies…
Krakatau voleano which is located at Sunda Strait, Indonesia, catastrophic The is a wellknown volcano in the world, because of its eruption in August 1883, and submarine caldera came into existence. Relatively in a short time, fortyfour years later, in Docamber 1927, ronewed activity was begun, started by submarine oxplosions. eruption was a commencement for the first periode of a now cycle of …
An eye-witness account on the eruption of the Mountain Krakatau on hundred yeansvaro is found in the form of a poen in two lithographed editions in Arabic script. Both lithographed Singaporean editions are found in the National Library, Jakar- ta. Each of then are called Inilah Syair Lampung Dinaiki Air Laut ("this is a poen about Lampung when it was flooded by the sen-water"s furthen mentioned…
Dutch reactions to the Krakatau eruption, a paper based upon some 19th century publications and upon archival material such as the series "mailreports" originating from the Dutch Ministry of Colonies and some private letters and reports. It presents a description of personal experiences of cye-witnesses, Dutch government regulations in connection with the Krakatau events, charity, and in an imp…
