The session on volcano-tectonics deals with any type of deformation (such as that induced by magma, tectonic forces, or gravity), at any scale, in subaerial and submarine volcanic areas. In particular, we hope that the contributions to this session will advance our knowledge of the physical processes responsible for, and thus help us make correct interpretations of, volcano deformation during periods of unrest.
The session includes, but is not restricted to, the following topics:
• relationships between volcanism and regional tectonics (in oceanic and continental rifts, arcs, back-arcs and hot spots);
• characteristics and mechanisms of caldera collapse, resurgence and unrest;
• conditions for dyke propagation, emplacement and arrest;
• modes of sector collapse of volcanoes;
• dynamics of formation of magma chambers, laccoliths, and other large intrusions;
• physical properties of volcanic rocks.
Particularly welcome are contributions based on results from fieldwork, remote-sensing studies, geophysical measurements, and analytical, analogue, and numerical models.
Some of the questions that we hope to address in this session are: (a) How can we make our surface-deformation interpretations more realistic, and what data are needed to make them so? (b) Which structural factors and processes have the greatest effects on magma emplacement and eruption? (c) How can we improve our knowledge of the infrastructures and mechanical behaviour of active volcanoes?
The session on Volcanotectonics also includes a subsession, suggested by
Dr S. Vinciguerra, entitled "Physical and mechanical properties of
volcanic rocks". Because of the vital importance of rock properties for
modelling and understanding volcanotectonic processes, contributions to
this subsession are particularly welcome.
