Overview

This documentation is for version 3.0.0-SNAPSHOT7 of The TauP Toolkit created Nov 04, 2024.

The algorithms employed within the TauP package are based on the method of Buland and Chapman [BC83]. The IASPEI ttimes package is a widely-used implementation of the methodology.

The main benefit of this new package is a marked increase in flexibility. It will handle many types of velocity models, instead of being limited to just a few. A new phase parser allows times to be computed for virtually any seismic phase. The use of Java enables this code to be run on a variety of machine and operating system types, without recompiling. This package also offers the extraction of derivative information, such as ray paths through the earth, pierce and turning points, as well as travel time curves.

A paper has been published in Seismological Research Letters, Crotwell et al. [COR98], that is intended to be used as a companion to this manual. While this manual mainly focuses on the praticalities of using the codes, the paper is able to go into more detail on the methodology. A pdf copy of this paper is also available in the distribution.
