Abstracts submitted for the Panga Meeting

2002 PANGA Investigator Meeting
November 14-15, 2002
Central Washington University
Ellensburg, Washington

The 2002 PANGA Investigator Meeting was attended by 28 scientists from institutions and agencies concentrated in the western U.S. but from as far away as New York state. The focus of this meeting was reflected in three special presentations and a working session: developing broader scientific perspectives, examining resource issues, and staging for Earthscope.

There were several highlights this year: Kerry Sieh delivered a keynote address on The subduction earthquake cycle: Paleogeodetic and paleoseismic evidence from Sumatra. Tom Brocher presented the goals of the NEHRP program relative to PANGA investigations. Dan Johnson and Dave Verdonck summarized their recent work on gravity studies and vertical leveling results respectively. Charlie Rubin gave a summary of recent field studies along the Denali fault rupture.

Thursday afternoon began with technical summaries of the networks by Herb Dragert and Andrew Miner. Both reported progress in densification of PANGA/WCDA. Mike Jackson talked about the shape of Earthscope and PBO implementation. Stephane Mazzotti presented a new subduction zone inter-seismic model.

Friday morning started off with a session devoted to developing a science plan for PANGA that will reside on the web and will be periodically updated through community feedback. Ray Wells contributed his summary of PANGA issues from the Earthscope and PBO planning workshops. This will provide a starting point for shaping the community science plan. We have decided to revisit a more formal organizational structure for PANGA efforts and the idea of an Executive Committee was floated. The PANGA core institutions will be invited to appoint a representative to that community: Cascade Volcano Observatory, Central Washington University, Oregon State University, Pacific Geoscience Centre, Rensselaer Polytechnic Institute, University of Idaho, University of Oregon, and University of Washington. The Executive Committee will meet early in the spring to take up a number of issues related to Earthscope prioritization and committees, proposal submission, and other coordination issues.

A poster session followed with contributions from Mike Caron, Noah Fay, Pat McCrory, and Ray Wells. Oral presentations by Ronnie Ning, Bill Sumner, Meghan Miller and Tim Melbourne focused on recent GPS results.

Follow-up activities include implementation of a PANGA Investigator Community page on the PANGA web site and web access to the list serve. Details of the presentations, attendees, and this report can be found at http://www.geodesy.cwu.edu/ on the Panga Community page.
