This session addresses a wide range of issues related to the evolution in time and space of volcanic processes, landforms and environments. By combining perspectives on geomorphology, geochronology and the volcanic lithofacies this session will allow a deep discussion of the processes which shape volcanic landscapes and better constrain the timescales and sequence of activities by which such morphologies are created. A specific focus of the session is magma-water-ice interaction, which can have dramatic impacts on landforms and eruption behaviour over a wide range of timescales.
