Develop an X-Windows Tool to Compute Gaussian Beam Synthetic Seismograms

Abstract

This report contains a description of progress made on the design of an X-Windows package for computing synthetic seismograms using the Gaussian Beam method. A summary of the functional flow and the basic architecture of the system formed the bulk of the first semiannual report for this project. Development has now reached the point that the user can create synthetic seismograms for two-dimensional velocity models created with the X-Windows interface. A module called Xgb is used to form and shape the two-dimensional velocity models and to trace rays through the medium. A second module, called GBseis, reads the raytracing results created by Xgb and computes synthetic seismograms according to instructions passed to it via interprocess communication (IPC) messages from Xgb. The IPC software and the code to view the results of the synthetic seismogram computation have all been developed previously under the NMRD. A final major step yet to be done is to incorporate SQL queries into the code to allow raytracing results and velocity models to be stored within an Oracle database like that which exists within the software environment at the Center for Seismic Studies.
