Predicted travel times of P wave of Magnitude 6.8 Earthquake of SIKKIM, INDIA 2011 September 18

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.
