The performance of a seismic network is linked with the quality and number of its stations. In Algeria, in order to implement a high quality network (ADSN), site selection and installation remain crucial taking into account many environmental aspects as security, radio link connections…etc.
From a database of seismic records collected from 2008 to 2016, an analysis year by year of the quality parameters of the several stations was carried out taking into account also the season's factor.
To monitor quality of the ADSN (Algerian Digital Seismic Network) stations, the noise level background is characterized for each station. The study includes seasonal and diurnal variations. Actually a web monitoring page help to control stations involved in the event location. A mobile application is also developed to different end users information relative of seismic events occurrence. In other hand, several technical works are made daily to test quality of the ADSN stations and to enhance the correct automatic event location. Among these tasks, state of health and rate of operation monitoring, seismometers and recorder calibration and sites selection for new broadband stations.
For nearby future, we plan to integrate existing stations and install new seismological stations for dams monitoring. Finally GIS (Geographic Information system) is set to manage the operation of our rapid warning system.
