[iris-bulk] Fall AGU sessions - S06 and S15

[IRIS]

Dear Colleagues:

We would like to draw your attention to a special session S06 at the  
Fall AGU
meeting on “temporal Earth-monitoring with seismic waves”. We  
encourage you to
submit an abstract focusing on observations, interpretations,  
theoretical
contributions and technical issues of the different approaches with  
the goal to
advance on the way to 4D Seismology. The deadline for abstract  
submission is
September 10th, 2008. Please feel free to forward to your colleagues  
that would
be interested in this topic. Thank you very much.

S06: Monitoring Temporal Changes of Earth's Properties with Seismic  
Waves

Sponsor: Seismology

CoSponsor: Geodesy; Mineral and Rock Physics; Tectonophysics;  
Volcanology,
Geochemistry, and Petrology

Description: Traditionally, seismic waves were used to investigate the  
3D
velocity and attenuation structure of the Earth. The detection of  
temporal
changes in the structure was out of reach. Recently, technical and
methodological developments led to a number of observations of such  
temporal
changes. The main targets are volcanoes, fault zones, and hydrocarbon
reservoirs. In most cases changes of the seismic velocities are  
monitored.
Techniques range from repeated structural studies like tomography or  
seismic
surveys to interferometric approaches that are specifically designed  
for the
detections of temporal changes. The latter group uses repeating  
earthquakes,
repeatable active sources like vibrators or ambient noise.

The observed velocity changes are attributed to migrating fluids, to  
seismicity
induced stress changes or to structural changes like damage in a near  
surface
layer.

To this session we invite contributions on temporal Earth-monitoring  
with
seismic waves. We want to focus on observations and their  
interpretations. But
we also want to discuss theoretical contributions and technical issues  
of the
different approaches with the goal to advance on the way to 4D  
Seismology.

Dear Colleagues:
We would like to draw your attention to a special session S15 at the  
Fall AGU
meeting on “Seismological Investigations of the 2008/05/12 Ms8.0  
Wenchuan
Earthquake”. This disastrous event was felt throughout the Eastern  
Asia, and was
responsible for killing at least 70 thousand people, and leaving  
around 5
million homeless. We invite contributions that take advantage of dense  
seismic
observations to study the mainshock slip distributions, aftershock  
locations,
local fault zone structures, regional-scale seismic tomography, near- 
field and
remote triggering, future seismic hazard in the surrounding region,  
and more.

The deadline for abstract submission is September 10th, 2008. Please  
feel free
to forward to your colleagues that would be interested in studying this
earthquake. Thank you very much.

Description: 	The 2008/05/12 Ms8.0 Wenchuan earthquake occurred in  
Eastern
Sichuan, China. It ruptured more than 300 km along the Longmenshan
fold-and-thrust belt that bounds the Tibetan plateau and the Sichuan  
basin. This
disastrous event was felt throughout the Eastern Asia, and was  
responsible for
killing at least 70 thousand people, and leaving around 5 million  
homeless. The
mainshock and its rigorous aftershock sequences were recorded by many  
permanent
and temporary seismic stations deployed by Chinese Earthquake  
Administration and
other institutions at local and regional distances, and the Global  
Seismic
Network and USArray at teleseismic distances. This session invites  
contributions
that take advantage of the dense seismic observations to study the  
mainshock
slip distributions, aftershock locations, local fault zone structures,
regional-scale seismic tomography, near-field and remote triggering,  
future
seismic hazard in the surrounding region, and more.
