Güralp Data Centre: Cloud-Based Data Acquisition and State-of-Health Monitoring for Seismic Networks

Operational seismic networks are required to deliver reliable, low-latency data and timely earthquake information while managing heterogeneous instrumentation, long-term data archiving, and evolving network and operational demands. Beyond waveform acquisition, network operators require comprehensive visibility of network state-of-health (SOH), latency, and data continuity in order to maintain catalogue completeness and rapid response capabilities.

We present the Güralp Data Centre (GDC), a data acquisition and archiving platform designed to support operational network monitoring by providing centralized access to real-time and archived seismic data alongside integrated SOH analysis tools. GDC aggregates SEEDlink data streams from distributed stations and provides time-based data interrogation, long-term performance metrics, and automated SOH reporting to support both day-to-day operations and long-term network assessment. GDC can be deployed either on Güralp-hosted cloud infrastructure or within a customer-managed cloud environment, allowing users to balance redundancy, scalability, and data control requirements. When accessed through the Güralp Discovery platform, GDC enables automated instrument registration, remote firmware and configuration updates across networks, and traffic-light dashboards for rapid assessment of station health, latency, and outages. We discuss how these capabilities address common challenges in network seismology, including remote station management, near-real-time data availability, and long-term network performance monitoring, and consider lessons learned for improving the reliability and responsiveness of seismic monitoring systems.
