Information
Aims, contents and method of the course
The goal of the course is to introduce various methods of seismic data processing, for which more than one seismic station is used with implications for structural studies. It starts with comparison of signals at two stations and proceedes to seismic arrays and large network data analysis. Each method is explained theoretically using intuitive sketches as well as described by equations. Examples of real data processing then follows. We demonstrate the processing steps showing representations in time domain, frequency domain, frequency-time spectrograms, filtered signals, envelope of the signals and others to emphasize different approaches to the same problem. Published papers are presented and implications for both structure and wave propagation are discussed. Advantages as well as drawbacks of the methods are presented.
