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.

 

Convenors :
