The Tethys Oceans separated the African, Arabian and Indian continents from Eurasia in Mesozoic-Cenozoic times. When the Atlantic Ocean opened, the continents started to converge and the Tethys Oceans gradually began closing.
Erupsi Gunungapi Kelud pada tahun 2007 diawali dengan peningkatan kegempaan pada September 2007 dan diakhiri dengan pembentukan Kubah Lava di Danau Kawah pada 3 Nopember 2007. Fenomena ini merupakan peralihan sifat erupsi, karena erupsi terakhir sebelumnya pada Pebruari 1990 bersifat eksplosif.

Ce travail a pout objet 1 etude de la circulation des eaux soterraines dans formations volcaniques pas methode PS.
The first is the present statement of the volcanological application ot the SP method. This method is typically used detect hydrothermal zones which exist when two conditions are filled up; presence of a heat source and of a zone with high permeability.
This study concern the quaternary geology, geomorphology and sedimentology of the intramontane Bandung basin, West - Java, Indonesia. A comprehensive analysis of the sequence of lacustrine, alluvial and volcaniclastic sediments in the basin form the basis for a reconsstrution of the Late Quanternary geologic and morphologic evolution of the Bandung basin area and for an evaluation of the geolog…

Pengamatan aktivitas seismik bumi menuntut ketepatan dan keahlian yang tinggi dari seorang pengamat. Pengamatan seperti picking dan penentuan lebar jendela yang sangat bergantung pada subjektivitas pengamat ini sangat sulit diterapkan pada sinyal gempa vulkanik, karena umumnya onset sinyal sering kali sulit terlihat.
The 1982-83 eruption of Galunggung Volcano (Java, Indonesia) represents a splendid example of syneruptive magmatic evolution. This eruption seems to be particular because of three characteristics: its duration (9 month) whereas historic activities lasted only a few hours of days, the diversity of the eruptive dynamics and the wide range of compositions erupted.
