We would like to invite you to contribute to the session we are organising at COV 10 (https://www.citiesonvolcanoes10.com/s1-28/ ) that will be held in Naples in September 2-7 2018:
S1.28 | Linking magmatic fragmentation to explosive styles and eruption intensities
Magmatic fragmentation is one of the leading process driving the explosivity of eruptions, controlling the size distribution of pyroclastic particles exiting the vent and strongly affecting dispersal of tephra. It is also a complex process, driven by the dynamic response of magma to shearing, cooling, and depressurization in the conduit. Because of intrinsic and extrinsic conditions, the dynamics of an eruption as well as the efficiency of fragmentation can vary significantly. Quantifying and forecasting fragmentation conditions and outcomes is a challenging but crucial task but for the quantification of the eruption dynamics and proper hazard assessment. For this reason, it requires a synergistic collaboration between different expertise and the application of field, laboratory, and numerical techniques.
In this session, we foster discussions on the understanding of fragmentation processes, their role in various eruptive dynamics (Hawaiian, Strombolian, Vulcanian to Plinian), and the contribution of pre-eruptive processes and magma properties in controlling the specific fragmentation regimes. In particular, we welcome contributions on:
· geophysical monitoring for real-time or high precision quantification of particle size distributions, and its relationship with the eruptive dynamics;
· field studies reconstructing size distributions of tephra deposits;
· studies linking particle shapes and textures to fragmentation conditions;
· experiments and numerical modeling studies defining conditions required for the onset of fragmentation regimes and their transitions;
· multidisciplinary techniques proposing novel models and approaches in unraveling the dynamics of magmatic fragmentation
