Advanced Seismic Monitoring Systems in Algeria: Integration and Innovations

The Algerian Seismic Network, operated by Centre de Recherche en Astronomie, Astrophysique et Géophysique, employs state-of-the-art seismic equipment, including 10 BB (STS-2) seismic stations under construction and various operational sites utilizing VSAT transmission and solar power. With real-time data reception via ADSL, telemetry, and comprehensive noise analysis using Antelope software, this network enhances earthquake monitoring and analysis. The ongoing development includes integrating GSM transmission, improved website features, and automatic alerts for seismic events.
