520 $a Multiple methods exist for modeling with synthetic seismograms, each with its own characteristic application; local and detailed; global and asymptotic; body and/or surface waves.
520 $a Events such as the nuclear tests in the Tarim Basin in China, recorded at regional distances require more than one such characteristic. A successful model would need detail close in and a global result. The ability to join two methods can therefore be very powerful.
520 $a Within this text the exploration is of finite difference and discrete wavenumber integration methods. The basis of the conversion between methods is the idea in Huygen's principle of representing a wave front as multiple sources, then propagated as an alternate method.
520 $a Modeling detail locally, finite difference eventually becomes computationally intensive or undetailed. Representation theory replaces finite difference with discrete wavenumber integration propagating to the receiver at a regional distance.
520 $a The requirement for multiple sources means that efficiency and optimization of methods are paramount.
