1 A (very brief) introduction to the shear wave inversion

2 From ANT dispersion to shear-wave velocity models
Ward et al. 2013

3 From ANT dispersion to shear-wave velocity models
Ward et al. 2013

4 From ANT dispersion to shear-wave velocity models
Minimize the misfit between observed and predicted dispersion data

5 Caution!!! All models fit data equally well! Dispersion fit = red
Dispersion data = black Very important to have a good initial model!

6 Shear-wave velocity map-slices and cross sections
Ward et al. 2013

Basis Functions. What’s a basis ? Can be used to describe any point in space. e.g. the common Euclidian basis (x, y, z) forms a basis according to which.

B-Trees. Motivation When data is too large to fit in the main memory, then the number of disk accesses becomes important. A disk access is unbelievably.
