Magmatic processes are known to operate across a range of timescales: from thousands to millions of years' residence and evolution within a magmatic plumbing system, through to the hours to minutes prior to eruption. Understanding the timescales of these magmatic processes, including accumulation, ascent, eruption, and final cessation of activity is vital for interpreting and responding to future magmatic activity. Together with thorough dating of deposits that reveal timing and frequency of past eruptions, this knowledge provides the foundation for improved hazard management in volcanic regions. By using a range of petrological, geophysical, geochemical and geochronological tools, increasingly detailed timescale constraints can be placed on past eruptive episodes.

In this session we invite submissions that examine magmatism and volcanism across a variety of timescales; from residence and rejuvenation within the crustal column, to eruptive triggering mechanisms and syn-eruptive processes, and their relation to the long-term timing and frequency of repeated activity.
