Recent research achievements and a typology of volcanic mountains in Hungary in Environmental and dynamic geomorphology.
Methods of investigation included the comparisons of the geology of landforms and drainage pattern analyses. The latter is valuable in the reconstruction of volcanic forms, since they reflect primary forms which govern the processes of denudation
. On the basis of preservation of original volcanic forms, the volcanic mountains of Hungary are classified. (DLO).

Description de l'éruption du volcan de boue d'Ajrantekjan dans la chaîne d'Aljat le 18 sept. 1977. Le long du chevauchement d'Aljat, les dimensions et l'activité des volcans de boue augmentent d'ouest en est. L'activité volcanique est déterminée par
Kvikuholf i gosbeltum Islands (Magma chambers in the volcanic zones of Iceland)
Considérations sur la formation et la dynamique des chambres magmatiques islandaises. Les volcans centraux sont essentiellement alimentés à partir de chambres peu profondes, elle-mêmes rechargées à partir de réservoirs situés à 8-10 km de profondeur
Etude portant sur les structures et les séries volcaniques, les formations explosives corrélatives de dépressions anciennes, et montrant que le Stromboli, volcan essentiellement sous-marin est beaucoup plus complexe que le type qui porte son nom.
Two different volcanic ash-falls of Allerod age in high Belgium
Applying the same method to different ash layers, two volcanic ash-falls of Allerod age are distinguished: the Brackvenn ash-fall (14C age: 10 830 45 a B.P.) and the Konnerzvenn ash-fall (14C age: 11 030 160 a B.P.). (LW).
Greetings from Iceland. Ash-falls and volcanic aerosols in Scandinavia
A brief account of ash-falls and aerosols from historical volcanic eruptions in Iceland that have affected Scandinavia is given with special reference to the noxious effects of aerosols from the Lakagigar eruption of 1783 registered in contemporary
Etablissement d'un modèle susceptible de rendre compte des événements volcaniques postglaciaires majeurs et de l'histoire tectonique de la presqu'île de Reykjanes (comparaisons avec les autres systèmes volcaniques islandais). La plupart des volcans
Glacier erosion and sedimentation in the volcanic regions of Kamchatka
During earlier glaciations the influence of volcanism on glaciers and frozen strata caused the specific conditions for subglacial eruptions forming strata of welded tuffs and pumices, and thick strata of debris-Recent and older glaciers in regions
of active volcanism are covered with large amounts of pyroclastic material. During intense melting of glacier ice, thick morainic deposits were formed. Similar conditions are found in Iceland, as described by Thorarinsson (1968, 1974) among others.
A high resolution seismic study in the northern Sicilian basin, between Cape Milazzo and Aeolian Archipelago emphasizes the connection between the sicilian metamorphic basement and the volcanic body. The sedimentary cover includes two units
: the well developped sedimentary sequence of Sicilian origin and the reduced Aerolian volcanic sequence. The volcanic sedimentary unit is affected by a series of slides| the partial denudation of the volcanic cone can explain the preservation of the initial
Following the description of evolution history, the mountainous landforms (6 volcanic subtypes and 4 non-volcanic subtypes) and the hill and basin landforms (4 various subtypes) are presented and mapped in the two north Hungarian Mountains. (DLO).
