Wolf and Cipar's Interpretation (1993)
Wolf and Cipar used Roller's arrival time picks and developed
a 2-D model. The model accounts for topography and near surface velocity
variations. They then used the model to generate predicted phases
and compared them with the real data. Their model did a fine job
of fitting the data.
The Interpretation
-
Crustal thickness of 45 km (thicker than the other two)
-
Crustal velocities of 5.9-6.8 km/s
-
Lower Crustal boundary at 30 km (deeper than Roller's, same
as Prodehl)
-
Upper mantle velocity of 7.95 km/s (fast for western US)
Wolf and Cipar believe that their model is the most realistic
because they incorporated the near surface variations and topography.
