A National Tsunami Warning Centre in Turkey (NTWC-TR) established at the Kandilli Observatory and Earthquake Research Institute (KOERI) under the ICG/NEAMTWS (The Intergovernmental Coordination Group for the Tsunami Warning System in the Northeastern Atlantic, the Mediterranean and connected seas region) initiative is operational since January 2012 based on MOD1 Tsunami Scenario Database and TAT (Tsunami Analysis Tool) received from EC-JRC through a collaborative agreement. NTWC-TR is also acknowledged as a Candidate Tsunami Watch Provider within NEAMTWS. The Centre is relying on a system on systems embodying seismic and sea level monitoring, tsunami modeling, message dissemination systems, preparedness and mitigation activities. Considerable improvement on the seismic and sea-level network has been achieved; the communication infrastructure at KOERI has been upgraded and now includes its own GTS system. Further improvement of the Tsunami Warning System at the NTWC-TR will be accomplished through KOERI's cooperation with EC-JRC and METU to improve the scenario database and through participation in the FP-7 Project TRIDEC focusing on new technologies for real-time intelligent earth information management to be used in Tsunami Early Warning Systems.
