Earthscope/USArray Imaging Science & CIG Seismology Workshop on Computational Seismology
Charles F. Knight Executive Education Center
Washington University, St. Louis MO
Tuesday, October 31 - Thursday, November 2, 2006
This workshop presented
theory, documentation and hands-on exposure to several programs of forward modeling
and direct imaging methods for teleseismic data. Because forward modeling is an
essential part of formal seismic inversion methods, the workshop presented 1-D and
3-D synthetic seismogram codes that are being prepared for community distribution
under the auspices of CIG. In addition, the workshop presented several direct imaging
methods that have been developed to make images of the lower crust, mantle, and CMB structures
using receiver functions or the elastic wavefield.
The workshop involved a combination of both instructional presentations on the methodology
and theoretical background of the computational algorithms presented as well as hands-on
demonstrations in multi-workstation classrooms. During the in-class tutorials participants
were able to run the programs and learn how they work in a practical sense.
In addition, the workshop involved group discussions that allowed for creative
brain-storming on the possible directions that computational seismology could take in the
and the means to discern what these best paths are.
