The Seismic Analysis Code

The Seismic Analysis Code (SAC) is one of the most widely used analysis packages for regional and teleseismic seismic data. For the first time, this book provides users at introductory and advanced levels with a complete guide to SAC. It leads new users of SAC through the steps of learning basic commands, describes the SAC processing philosophy, and presents its macro language in full, supported throughout with example inputs and outputs from SAC. For more experienced practitioners, the book describes SAC's many hidden features, including advanced graphics aspects, its file structure, how to write independent programs to access and create files, and much more. Tutorial exercises engage users with newly acquired skills, providing data and code to implement the standard methods of teleseismic shear-wave splitting and receiver function analysis. Methodical and authoritative, this is a key resource for researchers and graduate students in global seismology, earthquake seismology and geophysics.

• Provides the first formalised introduction to SAC, combining an easy-to-use synthesis and tutorial guide
• Documents all aspects of SAC, from basic viewing of seismic data, to advanced use of macros, graphics, signal-processing sub-processes and much more – creating a key resource for all levels of users
• Includes reference to commonly used seismic analysis tools such as shear wave splitting and receiver function analysis, enabling readers to use SAC in conjunction with external software
