This research continues the development, implementation, testing and application of codes for both acoustic and elastic 3- D finite-difference and pseudo-spectral modeling and imaging of both earth structure and earthquake sources. Applications of the modeling include simultaneous simulation of both body and surface wave data recorded on crooked refraction profiles, data recorded in bore-holes, and whole-earth simulations. Applications of the imaging include migration of 3-D controlled source data in both stacked and pre-stack form, and imaging of earthquake sources in both time and space. These capabilities will be used by oil and mineral industries and by earthquake and tectonic investigations.

这项研究继续发展，实施， 测试和应用程序的声学和弹性3- 三维有限差分和伪谱模拟与成像 地球结构和地震源。 的应用 建模包括同时模拟身体和表面 在弯曲折射剖面上记录的波数据，记录的数据 在钻孔和整个地球的模拟。 的应用 成像包括三维受控源数据在 叠加和叠前形式，以及震源成像， 时间和空间。 这些能力将被石油和 矿业和地震和构造调查。
