<strong>Surface</strong> wave model developed using cluster analysis<br />
We have developed a new, very large global<br />
surface wave dataset build using a new,<br />
efficient measurement technique that employs<br />
cluster analysis<br />
distance<br />
envelope functions for Rayleigh 20mHz<br />
time<br />
grouped by similarity<br />
cluster trees<br />
Measurement algorithm<br />
§ “Undisperse” using a 1-D phase velocity curve<br />
§ Correct for source phase and amplitude<br />
§ Correct for predicted phase shift from 3D<br />
structure using a nominal phase velocity map<br />
