Historic Earthquakes: Travel Times

Magnitude 6.8 NEAR THE COAST OF CENTRAL CHILE
2003 June 20 13:30:38 UTC

Theoretical P-wave Travel Times

This map shows the predicted (theoretical) travel times, in minutes, of the compressional (P) wave from the earthquake location to points around the globe. The travel times are computed using the spherically-symmetric IASP91 reference earth velocity model. The heavy black lines shown are the approximate distances to the P-wave shadow zone (103 to 140 degrees).
