KOERI

Kandilli Observatory and Earthquake Research Institute is a multi-disciplinary scientific institution in Istanbul associated with Bosphorus University. It operates an observatory, seismological monitoring network, geophysical laboratories, and tsunami warning capabilities, contributing to earthquake research and hazard mitigation across Turkey and the surrounding Aegean Sea, Marmara Sea, and Black Sea regions. The institute collaborates with international organizations and national agencies in seismic risk assessment, engineering seismology, and public safety.

History

Founded in the late 19th century as an astronomical observatory, the institute traces roots to the imperial scientific initiatives of the Ottoman Empire and subsequent modernization efforts in the early Republic of Turkey. Over decades it expanded from astronomy to include geophysics, seismology, and earthquake engineering, responding to major events such as the 1939 Erzincan earthquake, the 1999 İzmit earthquake (also known as the 1999 Gölcük earthquake), and other significant seismic events in the Anatolia region. Institutional reforms in the mid-20th century and affiliation with Bosphorus University strengthened its research mandate and led to the establishment of specialized laboratories, a comprehensive seismic network, and partnerships with bodies such as the United Nations agencies, the European Union, and global seismological centers.

Organization and Facilities

The institute is organized into departments for seismology, geodesy, tsunami research, geotechnical engineering, and astronomy, and maintains administrative ties to Bosphorus University. Facilities include seismic data centers, clean rooms for instrument calibration, geodetic GNSS stations, oceanographic tide gauges, and historical astronomical instruments maintained for heritage and education. The campus hosts lecture halls, visitor exhibitions, and memorials related to seismic disasters like the 1999 İzmit earthquake and earlier catastrophes, facilitating collaboration with entities such as the Turkish Disaster and Emergency Management Presidency and municipal authorities in Istanbul.

Seismological Network and Instrumentation

The institute operates a dense seismic network covering western Anatolia, the Marmara Sea, and adjacent maritime zones, integrating broadband seismometers, strong-motion accelerographs, and real-time telemetry to regional data centers. Instrumentation includes long-period sensors for studying tectonic events related to the North Anatolian Fault, high-rate GNSS receivers for co-seismic displacement measurement, and pressure sensors for tsunami detection in the Aegean Sea and Black Sea. Data flows into automated event detection systems that interface with international catalogs maintained by organizations such as the International Seismological Centre, the European-Mediterranean Seismological Centre, and the United States Geological Survey. The network supports rapid hypocenter location, moment-tensor inversion, ground-motion intensity mapping, and real-time alerts for civil protection agencies.

Research and Activities

Research spans seismic hazard assessment, rupture mechanics, earthquake early warning algorithm development, paleoseismology, and risk mitigation studies for critical infrastructure in cities like Istanbul, Izmir, and Bursa. Projects have included probabilistic seismic hazard analysis for transport corridors, site response studies for major ports, and investigations of submarine landslides in the Marmara Sea that could trigger tsunamis. The institute publishes peer-reviewed studies collaborating with universities such as Istanbul Technical University and Middle East Technical University, and participates in European research frameworks, cooperative drills with NATO civil protection structures, and data-sharing initiatives with the Global Seismographic Network. Applied work supports revisions to national building codes and retrofitting strategies for heritage sites like those in Edirne and Safranbolu.

Education and Public Outreach

The institute hosts graduate programs, workshops, and public lectures aimed at students from institutions including Bosphorus University, Istanbul University, and regional technical colleges. Outreach includes earthquake preparedness campaigns, school programs, interactive exhibits on seismic waves and tsunami dynamics, and digital platforms for real-time seismicity maps used by journalists, emergency responders, and the public. Collaboration with media outlets and municipal disaster offices amplifies messaging on retrofitting, evacuation planning, and early-warning procedures inspired by lessons from events like the 1999 İzmit earthquake and global case studies such as the 2011 Tōhoku earthquake and tsunami.
