Krakatau and the Tectonic Importance of Strait Sunda
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…

Paleomagnetic Measurement and Radiometric'' Dating of the Volcanic Material 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…

Geomagnetic Survey at Two Volcanic Regions in Indonesia Krakatau Caldera and …
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…

Some Charecteristics of Brown Soils on Rakata islands developed in material O…
Four pedons of Brown Soils originating from material prior to the 1883 Krakatau eruption have been identified in Rakata, exposed or buried under the thick layer of pumiceous anh. Three of those pedons have been studied in terms of their physico-chemiopl proper ties, cand and clay mineralogy. The results indicate that the Brown Soils have been developed from basalto-andesitic volcanic motoria…
