Dear Colleagues,

We'd like to encourage you to submit a contributed abstract for session G02, "From Microns to Meters and Milliseconds to Days: Towards Integration of High-Rate GPS Measurements and Real-Time Seismic Data" to be held at the 2007 Fall AGU meeting in San Francisco.  The goal of this session is to bring together researchers from a variety of backgrounds to present work related to the collection and use of high rate GPS data and its integration with seismic observations.  We look forward to your contribution on this important and timely topic.

Abstract submissions are due Sept. 6, 2007.  More information can be found at http://www.agu.org/meetings/fm07/.

Best Regards, 
Jessica Murray, John Langbein, Peggy Hellweg, and Paul Bodin

G02 - From Microns to Meters and Milliseconds to Days: Towards Integration of High-Rate GPS Measurements and Real-Time Seismic Data

Conveners: J. Murray, J. Langbein, P. Hellweg, and P. Bodin

Session description:

In recent years GPS data sampled at 1 Hz or greater have provided valuable constraints in a variety of crustal deformation studies. Combining high-rate GPS data with recordings from inertial seismometers significantly expands the observable frequency and amplitude range of ground motion. Using these data types together could greatly improve rapid assessment of tsunami threat, ground failure, finite fault sources, volcanic activity, and immediate postseismic stress-transfer. However, although increasingly available, real-time high-rate GPS data have yet to be fully integrated with seismic data for monitoring and event response. This session will explore current capabilities and future directions for effectively using high-rate GPS data in these contexts, especially, but not limited to, their use in combination with seismic observations. We encourage submissions that combine these data types for monitoring, event response, and calibration, describe useful innovations for collection and processing (particularly of GPS observations), or characterize expected accuracy and ways to improve it. Furthermore, we seek submissions that present results from scientific investigations using high-rate GPS data, that assess the contribution of high-rate data to such studies, or that propose new applications for these observations.
