1. Tsunami warning agreements with the CTBTO Presented at the Eighth meeting of the Working Group on Tsunamis and Other Hazards Related to Sea-Level Warning and Mitigation Systems IOC/TOWS-WG-VIII 12 - 13 March 2015, Morioka, Japan Martin Kalinowski Capacity Building and Training Section International Data Centre Division Provisional Technical Secretariat of the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) Vienna International Centre, P.O. Box 1200, A-1400 Vienna, Austria

4. Elements of the CTBT Verification Regime International Monitoring System 321 stations: seismic, hydro-acoustic, infrasound, radionuclide IDC&GCI Consultation and Clarification Right to clarify matters indicating possible non-compliance On-Site Inspection Conduct of on-site verification activities Confidence Building Measures Large chemical Explosions: Prevent misinterpretations and calibrate seismic IMS component IFE = Integrated Field Experiment 3 November - 9 December 2014

5. The complete International Monitoring System: 337

6. Demonstrated effectiveness of the International Monitoring System Xenon-131m and xenon-133 Detected at Takasaki, Japan, and Ussuriysk, Russia Estimated date of fission coincides with 12 February 2013 DPRK site identified as possible source using ATM Error Ellipses for 2006, 2009 and 2013 DPRK Announced Nuclear Tests

7. Civil and Scientific Applications International Monitoring System data can be applied for Tsunami warning Sumatra December 2004 Aviation hazards Eyjafjallajokul March 2010 Urals February 2013 Meteorites Fukushima March 2011 Radiation releases Earthquake monitoring

8. Emergency Preparedness and Response After Fukushima Accident Level 5 Level 4Level 3 Level 1 and 2 This picture show time development of detections for each day after the accident. Level 5 = multiple fission products detected, Level 4 = one fission products detected, Level 3 = fission products typical for the station detected. Level 1 and 2 = only natural radioactivity detected CTBTO member of the Inter-Agency Committee on Radiological and Nuclear Emergencies (IACRNE) since 14.3.2012 CTBTO operates a unique global network of highly-sensitive detectors of atmospheric radioactivity.

9. II. Tsunami warning with IMS data

10. Tsunami Arrangement/Agreement: Present Status map Data forwarding configured for 14 Tsunami Warning Centres in 13 States Australia France Greece Indonesia Japan Malaysia Myanmar Philippines Republic of Korea Russian Federation Thailand Turkey USA Currently 98 stations are used for TW.

11. IDC/CBT Data Forwarded to each Tsunami Warning Center The Numbers above each bar indicate the number of Centres actively receiving data (>0 MB) in that year. NOTE: the USA has TWO centres (Hawaii and Alaska) however the total count for USA is only shown once. Conclusions: The number of tsunami warning agreements is increasing as well as the volume of IMS data used for this purpose.

13. Data Delay: Transmission CTBTO/IMS:30 seconds at most Page 13 Conclusions: The IMS data are rapidly available.

14. Data Delay: Receipt CTBTO/IMS:30 seconds at most LISS:100 seconds on average IRIS:180 seconds on average Source: N. NISHIDE NWPTAC Japan Page 14

15. Summary The number of tsunami warning agreements is increasing: 14 tsunami warning centres. The volume of IMS data used for this purpose increases: >2 TB/y from 98 stations. More tsunami warning centres are encouraged to seek an agreement with the CTBTO.
