Northwest Iran is one of seismically active regions in Iranian plateau and has experienced many destructive earthquakes in the past centuries. Since 1996, the Institute of Geophysics, University of Tehran has deployed a telemetric seismic network in northwest Iran. The main purpose of the network is the acquisition of seismic data originated in a set of eight remote seismological stations, and investigation of the origin of processes that cause earthquakes in this region. The data is transmitted from each remote station through telemetric link to a central station located at Fatabad near Tabriz city where all the information is processed. In this paper, an overview of the northwest seismological network in Iran is presented and the instrument response is calculated by applying a synthetic signal (sine wave) which consists of different frequencies with uniform amplitude (unit volt) to the system as input. The new seismological network has been oriented towards forecasting and warning capabilities concerning earthquakes. It is to study the spatial and temporal seismic distribution to identify seismogenic sources, its mechanism and geometry; and to create public awareness about the causes, effects and mitigation of natural hazards.
