First, we prove the validity of the decomposition of the wavefield in the presence of general anisotropy. Then we use it to derive the reduced 2-D equations of motions and discretize them using the ...

Abstract: Seismic anisotropy is evidenced in the inner core, upper mantle and the lower crust in large scale, and the evidence is generally provided by shear wave splitting analysis. Here this paper ...

VBM is an efficient exact wave propagation technique that has an O(n) compute and space complexity. Inherently produces globally optimal paths to all grid points. Solves several shortcomings of ...

In contrast, Biot’s poroelastic theory enables seismic wave propagation modeling across a broad frequency range. Methods: To evaluate poroelastic effects in seismic monitoring, we compare elastic and ...

Migration methods are fundamental to seismic imaging. Generally, seismic migration imaging methods can be categorized in pre-stack and post-stack techniques that are based on either wave-equation or ...

Seismic wave calculations are critical in designing buildings that can withstand earthquakes, protecting lives and minimizing damage. By analyzing how seismic waves travel through the ground ...

Brian Stump's primary research interests include seismic wave propagation in the near-source (hundreds of meters to tens of kilometers) and regional (hundreds of kilometers) distance ranges, seismic ...
