The aim of a seismic study determines the type and quality of the required seismic data. Design of a seismic network affects the quality of the recorded data. SeisAnalysis AS uses different criteria for the optimal design of seismic and geodetic networks. The frequency band of the recording instrument is the main criterion. Configuration of fault systems and seismic radiation patterns are among the important criteria. It is necessary to consider radiation patterns during micro-seismic studies. Other factors include data transmission, ambient noise level, maintenance, and ease of access in the field.
