Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Two more AGU session announcements: T23 and S13 (abstract deadline Sept. 6)

Date: 09/04/2007

Dear Colleagues,

Please consider submitting an abstract to one of the following sessions at AGU this December. We all look forward to stimulating presentations and discussion.

To contribute to these sessions, please submit your abstract online at http://www.agu.org. The deadline for abstract submission is September 6th. Please contact one of the conveners if you have questions.

Session T23: Stress in the lithosphere: Top-down or bottom-up control?

This session is sponsored by Tectonophysics, Seismology, Mineral and Rock Physics and Geodesy.

This session highlights new constraints on the origin, distribution and magnitude of stress in the lithosphere. It is clear that deviatoric stress and its sources can differ dramatically from one tectonic environment to another and we wish to better determine both the origin and rheologic controls on these stresses driving deformation of the continents. We especially encourage presentations that address the relative strengths of the crust and lithospheric mantle and thereby the role of each in controlling the rate and style of lithospheric deformation. Contributions from theoretical, observational, and modeling studies are all welcomed, in particular those that use multiple complementary data sets.

Session S13: Earthquake Early Warning: Design and Application Around the World

By the time the meeting of the American Geophysical Union convenes in San Francisco this fall, Japan will have launched its publicly available earthquake early warning system adding to the growing list of nations using early warning technology to mitigate seismic hazard.

Session S13: "Earthquake Early Warning: Design and Application Around the World" will bring together seismologists, engineers, social scientists and lawyers who are working to develop and implement early warning systems in Greece, Italy, Japan, Mexico, Romania, Switzerland, Taiwan, Turkey, the Unites States and elsewhere to discuss methodologies, limitations and best practices.

The science and engineering of rapid earthquake detection and notification has been developed substantially around the world in the last few years. Operational warning systems now provide seconds to tens of seconds warning prior to damaging ground shaking in Japan, Taiwan, Turkey, Romania and Mexico. New systems are also being designed and tested on existing realtime seismic networks in Asian, Europe and the Americas.

In this session we will bring together scientists, engineers and social scientists working on realtime seismic hazard mitigation to share perspectives, techniques and lessons learned.
