EGU 2011 Session: Volcano deformation, dynamics and deep structure
From: Giuseppe Puglisi <giuseppe.puglisi@xxxxxxxxxx>

Dear Colleague,

we would like to encourage you to contribute with a presentation to the session on Volcano deformation, dynamics and deep structure" (GMPV10 / G3.11 / NH2.7 / TS1.8) at the EGU Meeting, 3-8 April 2011, to be held in Vienna, Austria  (for details:  http://meetings.copernicus.org/egu2011/).

This session embraces studies in Structural Geology, Tectonics, Volcanology, Geodesy and Petrology.
A description of the session is provided below.

Deadline for receipt of abstracts is 10 January 2011.

The conveners are Valerio Acocella (University Roma Tre, Italy), Agust Gudmundsson (Royal Holloway London, England), Giuseppe Puglisi (INGV Catania, Italy), Tom Walter (GFZ Potsdam, Germany) and Sigurjon Jonsson (Kaust, Thuwai, Saudi Arabia).

Please pass this information on to colleagues and students working in this field.
We apologize for any multiple posting and look forward to meet you in Vienna.

Thank you.
Kind regards,

Valerio Acocella, Agust Gudmundsson, Giuseppe Puglisi, Tom Walter, Sigur Jonsson

Volcano deformation, dynamics and deep structure” session
conveners: Acocella Valerio, Gudmundsson Agust, Puglisi Giuseppe, Walter Tom, Jonsson Sigur.

 The session Volcano deformation, dynamics, and deep structure deals with the documentation and modelling of the deformation, dynamics, and internal structure of volcanoes. The focus is on advancing our understanding of current deformation of active volcanoes through data and models as to their dynamic behaviour and internal structure. All types of surface deformation are of interest, including elastic inflation, deflation, as well as caldera and flank collapses. The dynamic behaviour includes stress measurements and modelling. As regards internal structure, topics of interest include near-surface parts, such as exposed in fault and caldera walls, as well as the deep roots and plumbing system of active and eroded volcanoes, as revealed through geophysical and geological studies. The loading conditions considered in this session include tectonic forces, magma, and gravity. Studies of both subaerial and submarine volcanic areas are welcome.

The principal aims are to understand how volcanoes deform, the associated dynamic behaviour, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geophysical and geodetic measurements, and analytical, analog, and numerical simulations.

The session includes, but is not restricted to, the following topics:

• volcanism and regional tectonics;
• formation of magma chambers, laccoliths, and other intrusions;
• dyke propagation, emplacement, and arrest;
• earthquakes and eruptions;
• caldera collapse, resurgence, and unrest;
• flank collapse;
• volcano deformation and hazard mitigation.
