CoV 8. Inferring volcanic processes and hazards from the study of pyroclastic deposits

Dear colleagues,
We would like to draw your attention to the following session (in the Hazards session; tephra - 1.II.B.2) to be held at the Cities on Volcanoes 8 meeting in Yogyakarta, Indonesia (9 - 13 Sept 2014): "Inferring volcanic processes and hazards from the study of pyroclastic deposits"
Session description:
Pyroclastic deposits
offer crucial information on the frequency and the magnitude of
past and modern
explosive eruptions. In addition, tephra products (i.e. deposits
of fallout and
pyroclastic density currents) record eruptive styles and
processes involved in
explosive volcanic events. Many previous studies have clearly
demonstrated that
tephra products provide important information for mid- to
long-term hazard
assessment purposes at dormant edifices. On the other hand, the
potential of
tephra studies for expertise during eruptive crises at active
volcanoes (in the
context of monitoring duties, e.g. for eruption scenario
definition) has
appeared only recently in the literature and is a promising way
to implement
other approaches (seismology, geodesy, gas surveillance etc.).
This session
aims at presenting conventional and novel techniques and results
that yield
quantitative information on eruptive timescales and processes,
as inferred from
the study of natural pyroclastic deposits (recurrence pattern
and style of
eruptions, eruptive budgets, conduit processes etc.) with
implications for
long- to short-term hazard assessment purposes, and for
monitoring
applications.
