The next IUGG meeting will be held this coming July 2-13, in Perugia,  
Italy. It should be a fantastic setting, and a great meeting. Full  
details on the IUGG and abstract submission are at http:// 
www.iugg2007perugia.it/. If you have not yet thought about attending  
the IUGG, please give it serious thought!

The deadline for abstract submission for the IUGG 2007 meeting in  
Perugia is approaching (February 28th). We invite you to participate  
to the Session JGS003: "Earthquake and Volcano Geodesy". We believe  
that this session will be during the second week of the meeting. We  
look forward to a stimulating, multi-disciplinary session.

JGS003:  Earthquake and Volcano Geodesy
Large earthquakes produce significant static and dynamic  
displacements that can be measured easily by modern space geodesy.  
The largest earthquakes, such as the 2004 Sumatra-Andaman Islands  
earthquake or the much older but even larger 1964 Great Alaska  
earthquake and 1960 Chile earthquake, may produce dynamic and static  
displacements detectable around the entire globe. A particular area  
of newly-recognized importance is the intermediate range between the  
seismic frequency band and the static displacements, for example the  
role of slow slip and early postseismic transients. High-rate GPS  
provides a new tool to investigate such phenomena. While volcanic  
eruptions and intrusions cause deformation that is more localized  
than for the largest earthquakes, displacements can be substantial  
and geodesy can provide critical information about the movement and  
accumulation of magma in the subsurface. Volcanoes display remarkable  
dynamism and variation in displacements, with a rich array of  
geodetically observable signals at a wide range of timescales.

This session will cover topics ranging from the use of geodetic data  
to study earthquake and volcanic sources and related effects such as  
postseismic deformation, to the impact of earthquakes or volcanic  
unrest on geodetic observables such as gravity, displacements, and  
the terrestrial reference frame.

Conveners:

Jeff Freymueller, University of Alaska Fairbanks
Geoff Blewitt, University of Nevada-Reno
Eric Calaid, Purdue University

PS. For students and young (early career) scientists who are US  
Citizens or Permanent Residents, there are travel grants available  
through the AGU. IUGG Meetings are a great opportunity to meet and  
interact with scientists from all around the world, and with a travel  
grant the meeting is surprisingly affordable. See http://www.agu.org/ 
meetings/STG/iugg_stg.html. Deadline is the same as for abstract  
submission, February 28.
