On the Relationship Between Tectonic Indications and Volcanism of the 1883 Krakatau Catastrophic Eruption, Sunda Strait, Indonesia

---

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 injected to the height of 11 kilome ters which were accompanied by detonations were the fore- phase of the catastrophic eruption that took place in August 1883. The eruption might be classified as Katmaian type where acidic tephras of cal- careous-alkaline magma composition were ejected. Mineralogically such kind of magma was associated with plagioclase granites to quartz diorites with Niggli's parameters of x = 30 - 40 Y = 35 - 40 z = 35 - 40 Si 245 305 and k = 0.25 - 0.36 . It was apparent that the magma source was similar to that of acid andecitic tuff of the pre-historic period.
