Develop An X-Windows Tool to Compute Gaussian Beam Synthetic Seismograms
Abstract
This report consists of two principal sections: an introduction in which the functional flow and the basic architecture of a prototype system for computing synthetic seismograms using the Gaussian Beam method are described, and a second section in which progress toward implementing that design is outlined. To maximize functionality, the design integrates as much as possible software already developed under the NMRD initiative: code for handling database transactions, inter-process communication and graphical display of seismograms are assumed to exist. The system has two modules. The first provides X-Windows graphics to allow the user to construct and manipulate two-dimensional earth models, and also to trace the propagation of seismic waves through those models. The second module computes synthetic seismograms and/or calculate traveltimes for models constructed with the first. It has no graphical component. The raytracing capabilities of the program have been found to be very fast, owing in part to the way the velocity model has been parameterized. Several figures demonstrating model construction and raytracing are included.... Gaussian Beams, Synthetic Seismograms, X-Windows tools.
