Efforts to compile a more comprehensive bibliography on the ill- famed Krakatau volcano are presently more rewarding than in the pre- viously given attsapts (Van Barem, 1931; Brodie, 1982; Da Nova, 1936, 1953; Kusumadinata et al., 1979; Nourn van Padang, 1951; Ongkosongo & Suwardi, 1981; and Soagiarto & Soegiarto, 1983). This because in the last quarter of a century (1960-1984) we are interpret…
The author (1981) put an interpretation of the 1883 Krakatau eruption from the standpoint of geophysics. In the present paper, mainly the generation of the tsunami in the eruption will be discussed to supplement the previous interpretation.
The 1883 eruption of Krakatau Volcano in the Sunda Straits was one of the most impressvive eruptions in human history.
In Anak Krakatau's fifty years of existence an evolutionary developmental growth of its geomorphology and a gradually changing silica-content in the effusive throughout its five decades of eruptive activity could be recognied (De Neve, 1980, 1981).
In the last days of Augst 1883 on of the world's largest cataclysmic eruptions took place : the volacanic complex of Krakatoa, in Sunda Strait between java and Sumatra was shattered ash as to produce striking atmospheric effects over the whole world for several years to come. To consequent tsunami devastated adjacent coasts.
Let me begin with a question: why is it that a university, traditionally charged with the academic functions of teaching and reseacrh, finds itself involved in environmental conservation?
The Sunda Strait is situated between the island of Java and Sumatra, connecting the Java Sea in the north and the Indian Ocean in the South. In the northern part the strait is narrower and shallower than in the southern part. The narrowest part in the north is only about 24 km wide with depth of less than 8 m.
Untuk mendapatkan hasil rekaman berupa data kegiatan Seismik gunungapi yang baik diperlukan pengecekan/perbaikan dan kalibrasi kembali pada semua peralatan seismograph yang dipakai disekitar gurunungapi tersebut.
Pengecekan dan kalibrasi ini sangat perlu diadakan mengingat sebagian besar dari peralatan seismograph itu terdiri dari peralatan yang menggunakan component elektronika yang sering dapat berubah karakteristiknya akibat panas yang disebabkan oleh lamanya pemakaian yang terus menerus, sebab gangguan cuaca atau bisa juga berubah yang disebabkan oleh menurunnya tegangan power (batere).
The topographic reconnaissance survey was carried out by us in March 15, 1983. The survey has utilized the modest available equipment for surveying, e.i. magnetic geologic compass and range finder. Altimeter was also used to determine the elevation. The survey was done in the morning between 7.00 to 8.00 am.
