A study of the product of hydromagmatic activity and their associated xenoliths has been made on the recent volcanic centres on the island of Flores and Faila, in the Azores, in order to define the geothermal context.
Les techniques nouvelles d'observation de la terre par satellite permettent d'ameliorer les etudes preliminaires de cartographie geologique en domaine volcanique comme en domaine sedimentaire et metamorphique. L'objectif du travail presente dans ce memoire est d'essayer de reconnaitre les produits volcaniques existant dans la caldera du complexe Tengger, Java-Est.
The vicinity of Punung has been chosen by the author as a subject for this paper, because it offers an interesting problem in sedimentation. In the Tertiary the area was a shallow marine basin which bordered on a landmass, at that time situated North of Punung.
Volcanism has played a central role in forming man's environment. In one side, volcanic disasters rank high among natural hazards especially in countries where active volcanoes do occur in densely populated areas. Pyroclastic flows and lahar flows have been important agents of death among the types of volcanic hazards.
Le volcanisme est peut-etre le processus geologiquele plus spectaculaire a l'echelle humaine, mais aussi souvent le plus meurtrier, deux raisons qui justifient les efforts pour mieux comprendre ce phenomene fondamental. Divers domaines des sciences de la Terre concourrent a la recherche en volcanologie.
The Idjen caldera is classed as a Krakatoa type or stratocone caldera and is characterized by a caldera floor, a caldera escarpment, and older volcanic forms. The caldera diameter rangers from 14 by 16 km at the rim to 11 14 km at the floor with a maximum depth of 709m.
The island of Flores, one of the Lesser Sunda Islands, is about 350km long and contains a large number of active or recently active volcanoes. Including Paluweh Island, there are at least 12 volcanoes with records of recent activity.
