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.
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 …
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.
Krakatau's eruptive activity reawakened as submarinu on December 29th, 1927, and after several brief pf longer cyclus of erosion and denudation the volcano finally rose above sea level definitely between Augst 11th - September 10th, 1930 as Anak Krakatau IV.
Volcanic hazards due to lahar flows were more devastating than those by volcanics strewn from Mt Galunggung; the products of the April, 1982 January, 1983 eruptions.t
The purpose of this field trip was to investigate the extent, thickness versus distance relationships, and source of a young scoriaceous air-fall deposit exposed in the vicinity of the Kamodjang geothermal field. This deposit was first noticed in October 1981, exposed along the highway through the Kamodjang area. The eruption of similar scoria in the future could endanger the village of Pangkal…
From the last two eruptions of Mt.Kelut, i.e. in 1951 and 1966, remarkable changes of the crater bottom were recorded. After the 1951 eruption a lowering of 79 m and after the 1996 eruption up upheaval of 43 m was found to have taken place, as measured at the deepest sections of the crater.
In january thin white smoke was enmitted with pressure. A medium scale discharge of smoke until 75 meters above the craterrim took place once and was repeated 4 x during february.
During the eruption cycle of 1967-1968 a new lavadome came into existence in the upper breach of Batang river (SW-slope) at an elevation of 2600. The extrusion of lava started on October 10, 1967, and the growth of the dome--being accompanied from time to time by small avalanches with a naximun dis-tance of 1.5 km. fron its source--lasted continuously and finally got an elongated shape (Figure …
