CoV7 Colima: The scientific, monitoring, and mitigation challenges of multi-stage eruptions
From: <Susanna.Jenkins@xxxxxxxxxxxxx>
****************************************************************************************
Dear all,
We would like to draw your attention to 'Session 1.8: The scientific, monitoring, and mitigation challenges of multi-stage eruptions' at the upcoming Cities on Volcanoes 7 conference in Colima, Mexico from 19-23 November 2012 (session description below). The session aims to bring together those involved in hazard and risk modelling, geological field studies, crisis response and stakeholders in risk-reduction to discuss the multi-disciplinary novel approaches required to respond to the threats posed by multi-stage eruptions in populated settings.
Early-bird registration has been extended until 12 August, and the abstract submission deadline is now 28 August (www.citiesonvolcanoes7.com). Please note that the word limit is 300 words without references, tables or figures, and that each participant may submit up to two abstracts with a maximum of one to be presented as an oral presentation.
Look forward to seeing you there!
Susanna Jenkins and Jean-Christophe Komorowski

Multi-stage eruptions involve different stages of contrasting eruptive phenomena in one sequence, which may occur as a drawn-out succession of escalating, fluctuating or declining activity. Each stage presents a new set of complications for monitoring, the accurate forecasting of likely eruptive behaviour, and for associated crisis response and mitigation. Recent advances in reconstructing past volcanic activity at subduction volcanoes have confirmed the frequent occurrence of such multi-stage eruptions. The ongoing eruption of Soufrière Hills Volcano is a prime recent example of a multi-stage eruption: multiple peaks in intensity and pauses in activity have presented significant management issues for the scientists in charge and for the affected population. The 2010 eruption of Merapi, in which rapidly escalating activity over 11 days culminated in a highly destructive paroxysm requiring the evacuation of more than 400,000 people, has been the most recent example of a multi-stage eruption.
Multi-stage eruptions, in particular those concerning volcanoes that threaten large cities or populated areas, pose specific challenges for volcanology in terms of understanding the processes that cause transient eruptive activity, assessing the potential for their occurrence, developing adequate monitoring strategies and decision-making for crisis-response and risk-reduction planning. In light of the 2004 Sumatra disasters and the 2011 Fukushima catastrophe, the volcanological community must continue to address those challenges taking into consideration the domino impacts of coupled scenarios as well as low probability scenarios of maximal impact at different temporal and spatial scales.
