Pumice flow of the 1883 Krakatau eruption occurs It at Small Rakata, Rakata and Sertung Islands, those which roughly correspond to the wall of Krakatau caldera, Indonesia. significantly differs in both mineral and chemical compositions against any other volcanic rock or ejecta of the Krakatau Group, those of which belong to Miyashiro's (1974) tholeiitic series. Meanwhile, lithic fragments of gr…
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 i…
Krakatau's eruptive activity reawakened as sub marine on December 29 1927, and after several brief or longer cyclus of erosion and denudation the volcano finally rose above sea level definetly between Augst 11 and September 10. 1930 as Anak Krakatau IV.
Krakatau was studied from September 10 - 12. The 1883 eruption produced a large non - walded ignimbrite deposit (ash - flow) which covers large areas of Rakata, Sertung and Rakata Islands. We landed on all three islands at accesible points and axamined coastal exposures of the 1883 deposit.
Setelah mengalami masa dorman sejak tahun 1911 (87 tahun), Gunung Ibu mengalami erupsi menerus sejak tahun 1998 hingga saat ini. Pada periode erupsi ini, aktivitas Gunung Ibu sangat dinamis. Data kegempaan menunjukkan kontinyuitas aktivitas suplai magma, erupsi, pembentukan kubah lava, dan guguran yang saling berkesinambungan. Di samping itu, data aktivitas termal dari citra MODIS juga menunjuk…
Renewed activities started on March 13 with an eruption, soon succeeded by bigger scale eruptions acoompanied by ejection of incandes cent lava fragments. Ash showers fell along the western coast of java adn sometimes on the Southern coast of Sumatera, depanding on the prevailing winds.

The National Geographic Society of the United States of America has awarded me a grant of $20,000 to carry out a detailed study of the volcanic deposits from the 1815 eruption of Tambora volcano in Indonesia. The eruption is the largest event of its type in history and caused widespread environmental effects.
