Travel-time curve calculation for the Spherical Earth (PREM Model)

I have used the Preliminary Reference Earth Model of Dziewonski and Anderson (1981) to calculate the travel time curve. This model is very robust in the sense that it is designed to fit a wide variety of data including free-oscillation, surface wave dispersion observations, , travel time data for a number of body wave phases etc. 2,146 more words
