Özet

By utilizing data from the National Seismic-Monitoring Network of Turkey, operated by AFAD (Disaster and Emergency Management Presidency, Ministry of the Interior), power spectra of 198 stations distributed countrywide are computed and probability density functions as well as diurnal, weekly, monthly and annual spectrogram-graphics, hence, are obtained. Observed noise levels are the result of natural background noise, cultural noise as well as instrument installation practice and equipment defects. Countrywide noise distribution is displayed on a map and noise models for Turkey are developed in the study. Various suggestions are also given for some of the technical problems deducted from noise analyses in relation to the construction of the station, equipment faults, and defects.
