Earthquake Travel Times: Specify Earthquake
NOTE: The Earthquake Travel Time Calculator is no longer working correctly. We appreciate your patience as we develop a replacement. Meanwhile, please see the TauP Java application that you can download and run on any Java platform.
Generate a listing of the times that phases arrived at your seismic station
from a specified earthquake.

When you exit your browser, these values will be stored on your hard disk. This information is stored in a file named cookies.txt, and the term used for this is saving "cookies." Only the computer that originally stored the information as a cookie can get it back again.
Travel times are based on the IASP91 earth model (Kennett, B.L.N. and Engdahl, E.R., 1991, Traveltimes for global earthquake location and phase identification, Geophys. J. Int., v 105, pp 429-465). The program was developed with help from Arthur Snoke and subroutines from Ray Buland (ftp hazards.cr.usgs.gov/tau/UNIX/tau.tar.Z). Note that times are approximate and that no ellipsoid corrections are made.
