Volcanology

Studies conducted in the period between 1983 and 1986 on the physical aspects of volcanology, including investigations of physical processes involved in magma transport, are reviewed. Eruptions that occurred during this quadrennium are discussed together with the studies of the methods of volcanic hazard assessment and prediction around active volcanoes. Consideration is given to advances made in the understanding of magma systems, including volatile components, as well as to studies on the atmospheric impact of volcanism. Tectonic controls of volcanism and the volcanic aspects of mineralization are also discussed.
