Seismic Network and Data Quality
Earthquake monitoring; Seismometer sensitivity; Instrument response; Ambient noise; Data latency
Measuring of ground motion provides the most essential observations made from earthquakes and the basis for research within seismology and earthquake engineering. The measurements are done by seismic stations that are equipped with sophisticated instruments and are placed at specific selected locations. The good quality of these data is obviously important but can only be achieved if many different factors are considered. Often, the approach is adjusted to the scientific or monitoring needs and the available funding. This section deals with systems of seismic stations, so-called seismic networks and data quality-related issues.

- The most complete coverage of these topics is probably given in the New Manual of Seismological Observatory Practice (http:/nmsop.gfz-potsdam.de), giving an overview, the theoretical background, as well as examples and information sheets. Textbooks on seismic instrumentation are Havskov and Alguacil (2010) and Scherbaum (2001). A textbook on data processing for earthquake seismology is Havskov and Ottemöller (2010). Stein and Wysession (2003) and Lay and Wallace (1995) also have relevant chapters.
