Dear colleagues,
We would like to draw your attention to the following session to be held at the Cities on Volcanoes 8 meeting in Yogyakarta, Indonesia (9 - 13 Sept 2014):
(1.II.B.1) Methods and Uncertainties in The Measurements of Tephra Deposits
Conveners: Raffaello Prof Cioni, Costanza Bonadonna, Arnau Folch, Graham Leonard, Kristi Wallace
The study of tephra deposits gives fundamental information on the
dynamics of explosive eruptions and on the processes that control tephra
dispersal and deposition. This includes how tephra is sampled in the
field for multiple purposes, as such samples are important for direct
tephra studies, health characterisation and the study of volcanic
impacts. This information is crucial to the definition and calibration
of new physical models of the eruptive process, and to the validation of
existing models to be used both for scientific and hazard assessment
purposes. Quantitative data on important source parameters like erupted
volume and mass, eruption rate, total grain size distribution, etc. can
be in fa ct directly or indirectly derived from the deposits, and the
study of observed and well monitored recent eruptions can turn out an
important tool for the definition and calibration of some general
methods for these measurements, and of the related uncertainties. These
measurements are of absolute importance also for the study of the past
activity at active volcanoes, where hazard assessment efforts should
strongly rely on a deep knowledge of their eruptive history. We propose
to convene in this session all those volcanologists who recently worked
on these topics, in order to revise the state of the art about the
quantitative study of tephra deposits, to present the most recent
studies and results, and to discuss the needs and the expectations of
the volcanic modeller community. The session should trigger an open
discussion that should be addressed to the common definition of some
best practices and protocols for the measurement and the estimation of
the different physical parameters of interest for a correct and complete
quantitative description of explosive eruptions.
The abstract submission deadline is Monday, April 14, 2014. Full details can be found on http://www.citiesonvolcanoes8.com.
