The data that are used by seismologists generally originate as seismograms, which are time series. I assume that you have a rudimentary understanding of time series analysis. This lecture reviews some of the many ways that time-series analysis is used in seismological research. The slides are on ANGEL.

You should have at least one good time series reference if you are a seismologist or geophysicist. The subject requires you to work through it though, not just casual reading. Fortunately, SAC, Matlab, and other tools enable you to explore the concepts relatively easily. Will look at SAC next class to help you get started.
