Antelope is an integrated collection of programs for data collection and seismic data analysis, and typically runs at the central processing site. It has been in development for over a decade and is deployed around the world.


The IRIS DMC distributes the Seismic Analysis Code (SAC) software for scientists conducting research using IRIS data. You must register with an online form to receive the SAC software.

SAC Version 101.6 introduced several new features including a new command parser that simplifies coding, improved precision for blackboard variables, colored fill for positive and negative portions of seismograms, and corrections of many errors and warnings.

Version 101.6a fixes bugs in v101.6 and adds a single-file PDF version of the SAC manual. Details can be seen from the detailed HISTORY of modifications files and brief overview of major CHANGES posted in the SAC project pages on SeisCode.


The TauP Toolkit is a seismic travel time calculator. In addition to travel times, it can calculate derivative information such as ray paths through the earth, pierce and turning points. It handles many types of velocity models and can calculate times for virtually any seismic phase with a phase parser. It is written in Java so it should run on any Java enabled platform. Unfortunately, gjc, which comes with many Linux distributions, is not quite Java and prevents TauP from finding its model files. Please use Java from Sun on Linux instead.
