TauP.R (version 1.5)

Earthquake Traveltime Calculations for 1-D Earth Models

Description

Evaluates traveltimes and ray paths using predefined Earth (or other planet) models. Includes phase plotting routines. The IASP91 (Kennett and Engdahl, 1991 ) and AK135 (Kennett et al., 1995 ) Earth models are included, and most important arrival phases can be evaluated.
