Each topic will be introduced with the basic theory followed by practical examples and exercises. There are manual exercises entirely based on the printed

Operation,ata collection has been described in NMSOP and Havskov and Alguacil (2006) and will not be repeated here. The processing can mainly be described as an interaction between the seismic data base and various processing programs (Fig. 10.1).

Introduction, is partly due to the general change of recording and storing of continuous data. This requires more processing and good organization of the data. It is very easy to sell new networks and usually some kind of processing software is thrown into the deal with some training. Some manufacturers’ softwar

Earth Structure and Seismic Phases,ith reliable timing appeared more than 100 years ago, they provided, through the observation of travel times, the first real evidence of the internal structure of the earth. Initially there were many unknown wiggles (phases) on the seismogram, however with better and better earth models, we now unde

Instruments and Waveform Data, data is produced and in which way the instruments limit the kind of analysis that can be done. In this chapter we will deal with the sensors and the digitizers since they are the only units that affect the processing of data.

Signal Processing,ced signal processing tasks. The data itself often requires signal processing in order to do simple tasks like filtering when picking phases. In the analog world it was common to have high gain SP records and a low gain LP record (see Chapter 3), which can be considered recording the signal with 2 f
