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…

Merapi Volcano in Central Java is the most active volcano in Indonesia. Eruptions have occurred very frequently (approximately once in a year as recorded since 1920) and it is situated in a densely populated area. Therefore it may be classified as a very dangerous volcano.
Volcanio gases are the primo mover of the eruptions which drags the magma up towards the earth's surface. And because of their much lower viscosity, volcanic gases are far more fast than the magma they come from to give some informa-tions.
