The map below shows the predicted travel times of the compressional (P) wave from the earthquake location to points around the world. Spherically-symmetric IASP91 reference earth velocity model are used to compute travel time. The travel time computed in minutes. The heavy black lines shown are the approximate distances to the P-wave shadow zone (103 to 140 degrees). The table below depicts theoretical P-Wave Travel Times in tabular form.
