Theoretical P-Wave Travel Times
Magnitude 4.7 CENTRAL CALIFORNIA
2005 September 22 20:24:48 UTC
Preliminary Earthquake Report
from the Advanced National Seismic System (ANSS)
These maps show 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).
