EGU 2011 Session: NH2.8 - Merapi volcano Central Java, Indonesia: dome collapses and centennial 2010 eruption

Dear All,
We wish to draw your attention to the EGU General Assembly 2011 Session " Merapi volcano Central Java, Indonesia: dome collapses and centennial 2010 eruption" convened by Philippe Jousset, Surono, Marie Boichu, David J. Schneider and Fabrizia Buongiorno. The assembly will be held in Vienna from 03 to 08 april 2011. Information about submitting an abstract to this session (deadline 10 January 2011, 24:00) can be found on the EGU website (www.egu.eu).
Session details :
Merapi volcano (Central Java, Indonesia) is
one on the most active strato-volcano in the world, located in a very densely
populated rural area and at 25 km north of the historical city of Yogyakarta.
Before 2010, known eruptions implied the growth and collapse of domes, with
generation of deadly “nuées ardentes”. These eruptions have been studied in
detail by many research groups in the world, with different techniques and
methods, including ground and space observations, numerical modelling, and
sociological approaches. The October-November 2010 eruption was very different
in many aspects. According to seismic records, the energy released during that
eruption was 100 times larger than any previously monitored eruption of Merapi
volcano. Space observations of ground deformations by means of high resolution
SAR data has been available for the first time at near real-time basis thanks to
the quick response from Space Agencies and GMES system. In addition to the usual
proximal hazards, this eruption also produced significant ash emissions that
resulted in widespread ash fall on communities and disruptions to air traffic in
the region. This large amount of deposits increased dramatically the threat of
number and size of lahars. This session is dedicated to highlighting
similarities and differences between previous eruptions and this last one.
Understanding the possible link between volcanic and tectonic activity at
various scales will also be of particular interest. We would like to make a
state-of-the-art of our scientific knowledge on Merapi volcano, in various
disciplines including geology, geochemistry, geophysics, tectonics, but also
risk analysis and socio-economics. We are seeking to gather researchers that
worked in the past and at present on Merapi volcano and who would be willing to
collaborate in future studies to make the link between various hazards and
risks. Despite a clear focus of this session on Merapi volcano, we also very
welcome studies of other volcanoes showing a similar eruptive
behaviour.
