1. An executable program contained on a computer-readable storage medium, the executable program containing instructions, which when executed by a computer, perform a process, comprising: simulating three linearly independent far field stress models for a subsurface earth volume; computing stress, strain, or displacement values for data points in the subsurface earth volume, based on a principle of superposition applied to the three linearly independent far field stress models; and predicting a stress attribute of the subsurface earth volume in real-time, based on the precomputed stress, strain, and displacement values.
