Caucasus Seismic Network
The Caucasus Seismic Network is a regional seismic monitoring system serving the Caucasus region, integrating observatories and institutions across Armenia, Azerbaijan, Georgia, Russia, Iran, Turkey and neighboring areas. It supports earthquake detection, seismic hazard assessment, tsunami warning coordination, and scientific research in collaboration with major organizations such as the International Seismological Centre, the United States Geological Survey, the European-Mediterranean Seismological Centre, and the Global Seismographic Network. The network interconnects national agencies, university research centers, and international projects to provide near-real-time seismic data and collaborative analysis for civil protection, infrastructure planning, and academic studies.
The system comprises distributed seismic stations, accelerometer arrays, broadband sensors, and telemetry links coordinated among agencies like the Geological Survey of Armenia, the Azerbaijan National Academy of Sciences, the Georgian National Seismological Network, and research institutions including Moscow State University, Istanbul Technical University, Tehran University, Leibniz Institute for Applied Geophysics, and the ETH Zurich. It interfaces with earthquake information services such as the European-Mediterranean Seismological Centre, the International Federation of Digital Seismograph Networks, the Incorporated Research Institutions for Seismology, and regional civil protection bodies including Emergency Situations Ministry (Russia), Ministry of Emergency Situations (Armenia), and municipal agencies in Tbilisi and Yerevan. Key scientific collaborations involve programs like GEOSS, NEAMTWS, and research consortia funded by the European Commission, the National Science Foundation, and bilateral grants with institutions such as the University of Cambridge and Columbia University.
Seismic monitoring in the Caucasus traces to imperial and Soviet-era observatories including the Pulkovo Observatory, the Institute of Geophysics (Tbilisi), and the All-Russian Scientific Research Institute of Geology and Mineral Resources. Post-Soviet transitions prompted modernization through initiatives with the World Bank, the European Bank for Reconstruction and Development, and collaborative projects with USGS and UNESCO to rebuild networks damaged by events such as the 1988 Armenian earthquake, the 1990 Baku earthquake sequence, and the 1999 İzmit earthquake. The 2000s saw deployment of broadband seismometers from manufacturers linked to Güralp Systems Limited, Nanometrics, and Kinemetrics, and integration with global programs like the Global Seismographic Network and the International Seismological Centre.
Stations typically host broadband velocity sensors, strong-motion accelerographs, seismic arrays, and GPS strainmeters from suppliers associated with Streckeisen, Trillium, Reftek, and Trimble. Telemetry uses VSAT links, fiber optics, and mobile networks interoperable with systems deployed by EUMETSAT, Inmarsat, and regional providers. Data centers employ processing software and toolkits developed in collaboration with IRIS, SeisComP3, ObsPy, and research groups at ETH Zurich and University College London. Redundant power and timing use GPS and GLONASS receivers alongside high-precision timing sources such as those maintained by institutes like BIPM and laboratories within Russian Academy of Sciences.
Real-time triggers and waveform telemetry feed into regional hubs that perform automatic detection, location, and magnitude estimation using algorithms derived from research at California Institute of Technology, Massachusetts Institute of Technology, Seismological Society of America publications, and software from USGS and EMSC. Databases are archived and shared through protocols compatible with FDSN web services, IRIS DMC, and national data centers in Yerevan, Baku, and Tbilisi. The network publishes rapid earthquake notifications, moment tensor solutions, and shake maps coordinated with agencies such as European-Mediterranean Seismological Centre, UN Office for Disaster Risk Reduction, and regional tsunami warning centers connected to IOC/UNESCO frameworks.
Research themes include tectonics of the Greater Caucasus, fault mechanics along the North Anatolian Fault, crustal deformation studies involving GPS campaigns coordinated with EUREF, seismic tomography projects in collaboration with Max Planck Institute for Geophysics and GFZ German Research Centre for Geosciences, and hazard modeling informed by paleoseismology from teams at University of Oxford, University of Cambridge, and Harvard University. Monitoring programs support urban seismic risk assessment for cities like Baku, Tbilisi, Yerevan, and Batumi, and infrastructure resilience projects linked to pipelines operated by firms such as BP and transport corridors like the Baku–Tbilisi–Ceyhan pipeline. Collaborative studies on induced seismicity engage bodies including the International Energy Agency and national ministries.
The network provides dense coverage across key seismic belts in the Lesser and Greater Caucasus, with station spacing varying by terrain and political boundary constraints. Performance metrics are benchmarked against catalogs from USGS, EMSC, and the ISC, with continuous improvements following major earthquakes such as the 1988 Armenian earthquake, the 2002 Caucasus events, and seismic swarms near Mtskheta and the Zagatala region. Notable scientific results include refined hypocenter relocations, crustal velocity models, and contributions to global earthquake catalogs used by the Global Earthquake Model project and hazard assessments by the World Bank.
Governance is a multi-stakeholder arrangement involving national academies like the National Academy of Sciences of Azerbaijan, the National Academy of Sciences of Armenia, ministries such as the Ministry of Environment and Natural Resources Protection of Georgia, and international partners including EU programs, the World Bank, and bilateral cooperation with institutions like USGS and Japan Agency for Marine-Earth Science and Technology. Funding mixes national budgets, international grants from organizations like the European Commission, research councils such as the Russian Science Foundation, and private-sector partnerships with energy firms active in the region. Coordination mechanisms draw on frameworks used by the European Mediterranean Seismological Centre and technical standards developed by the FDSN and ISO.
