A group of Ar-K dating data of volcanic rocks in Taiwan Island is listed in this paper, which clarifies the data of volcanic activity. This volcanic activity is closely related with plate movement since Mesozoic. Now there are still manifestations
of volcanic actions such as hot springs or fumaroles or solfataras.
Le Vésuve est le premier volcan qui ait fait l'objet d'une reconnaissance topographique et altimétrique précise. Suite à cette considération, l'A. présente de façon minutieuse les premiers travaux sur la représentation scientifique du volcan. - (MR)
The time series of volcanically produced sulfate from the GISP2 ice core is used to develop a continuous record of explosive volcanism over the past 110,000 yr. 850 volcanic signals (700 of these from 110,000 to 9000 yr ago) are identified

The chronology of volcanic events and the gradual retreat of the glacier are associated with a group of landforms that were formed mainly by interposing volcanic and glacial processes. This paper proposes a model of the post-Little Ice Age
A partir des images enregistrées par le satellite GOES-8, étude des différentes limites du panache de cendres et analyse de ses effets ssur une aire de 100 km de rayon autour du volcan Popocatépetl. Celle-ci a été la longueur moyenne des émissions

This paper examines the use of geomorphology in the creation of volcanic hazards maps prior to this eruption, the mitigation strategies used, and the subsequent role of geomorphology in subsequent recovery efforts. A sediment budget is presented

the distribution of snowpatches at 2 topographically different sites, one previously glaciated and the other a young volcanic landscape that has remained unglaciated since the central caldera erupted, forming the basis of the present topography. The need
In central Nigeria the Fluviovolcanic Series of the Jos Plateau are composed by deeply weathered volcanic rocks and sediments. The sequence is often capped by ferricretes. Changing groundwater conditions, that may be the result of plateau uplift

The development and results of the natural processes in the hard rock and weak rock areas of volcanic Putorana Plateau were studied by Czech - Austrian - Russian expedition. Intensive frost weathering causes, the degradation of glacial land forms
