Arc-Parallel Mantle Flow in Central America
Shear-wave splitting observations and tomographic imaging of anisotropic fabric, along with Pb and Nd isotrope data, provide strong evidence for the presence of arc-parallel mantle wedge flow beneath Nicaragua and Costa Rica. Such a pattern contradicts that predicted from classical 2-D corner flow.

Synthetic Shear-wave Splitting Program
Visualizing the effects of anisotropic structure on shear-wave particle motion is extremely beneficial in obtaining an intuition for the phenomenon of shear-wave splitting. I have developed a Matlab program, SynthSplit, that allows anyone to generate their own split shear-waves. Feel free to download the code.
