2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 From: Sara Barsotti <sara@xxxxxxxx> 2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2-2 Dear Colleagues, After few years of work, we are here to announce a merger of the IAVCEI Commission on Tephra Hazard Modeling and the Commission on Explosive Volcanism. CEV is one of the oldest commissions established within IAVCEI and its aim is to encourage and support studies and investigations on the wide range explosive eruption phenomena: from observations, dynamic processes and modelling, to hazard assessment. The THM Commission focused on a more specific goal of supporting field observations and the use of quantitative models of tephra-producing eruptions. We believe a merging between the two commissions will allow a more coordinated effort and will reinvigorate an active international network interested in all aspects of explosive volcanism topics. Specific themes or hot-topic research areas will possibly activate Working Groups within the CEV. These will get full support from the Commission for the duration required to accomplish focused goals in the research framework. All the current leaders of the two Commissions as well as the two Secretariat of IAVCEI strongly support the idea of the merging, but with this email we also want to make sure that any colleagues not happy about this decision will get the chance to comment. So, please feel free to contact any of us for additional comments. We also want to get the chance to remind you, once more, about the physical volcanology session planned for the upcoming IUGG General Assembly in Montreal, Canada, 8â??18 July 2019. This is the first event organised within the new established Commission on Explosive Volcanism. *Fostering the integration of deposit and modeling studies to investigate the subaerial processes of explosive eruptions* [Session V07] http://iugg2019montreal.com/v.html 27th IUGG General Assembly |International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI) > V| 2019 - MONTREAL, CANADA <http://iugg2019montreal.com/v.html> iugg2019montreal.com 27th IUGG General Assembly |Home| 2019 - MONTREAL, CANADA <http://iugg2019montreal.com/> iugg2019montreal.com Beyond 100: The next century in Earth and Space Science. The 27th IUGG General Assembly will be held July 8-18, 2019 at the Palais des Congrès in Montréal, Québec, Canada. V06 â?? Linking Volcano-Sedimentary Features with Eruptive Processes . Convener: Gabor Kereszturi (New Zealand) Co-Conveners: Guilhem Amin Douillet (Germany), Gro Birkefeldt Møller Pedersen (Iceland) Description. Volcaniclastic sediments encompass all primary pyroclastic rocks and deposits that formed in relation with volcanic eruptions, and successions remobilized during a volcanic eruption ... Understanding the dynamics of explosive eruptions is of paramount importance for the assessment of volcanic hazard and a major key to improve our knowledge is the study of resulting pyroclastic deposits. On one side, we know that differences in properties such as grain size, vesicularity, clast morphology and deposit geometry clearly reflect different transport and depositional processes. For example, Prof. Walker showed how grain-size characteristics and dispersal area of a pyroclastic deposit can be used to infer eruption discharge rate and intensity. On the other side, we have to face the problem that preservation of deposit is typically incomplete and, for the interpretation of such partial information about past eruptions, modeling of subaerial explosive eruptions can be extremely helpful. For example, application of inversion techniques to numerical models of ash dispersal is showing promising results. In this symposium, we encourage contributions from both field volcanologists and modelers to investigate how deposit studies can support the understanding and the modeling of volcanic processes and how modeling studies can help in the interpretation of deposit properties. We warmly invite you to submit an abstract and join this discussion. The deadline for abstracts and travel grant applications is *18 February 2019* *before midnight CET*. We look forward to seeing you there and planning the next community-wide workshop on explosive volcanism.
