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.
