NEAMTWS Tsunami Warning and Mitigation System for the

NEAMTWS – Tsunami Warning and Mitigation System for the North-Eastern Atlantic, Mediterranean and Connected Seas Recent Activities

The ICG/NEAMTWS was established as subsidiary body of the IOC, at the 23 rd Session of the IOC Assembly in June 2005 through the Resolution XXIII-14

WG 1 – Hazzard Assessment, Risk and Modelling WG 2 – Seismic and Geophysical Measurements WG 3 – Seal Level Measurements WG 4 – Advisory, Mitigation and Public Awareness

4 th ICG/NEAMTWS ASSEMBLY (LISBON) DECISIONS AND RECOMENDATIONS Improve seismic monitoring capability in North Africa Establish a Team-Task to define the RTWC architecture, prepare developing plans and evaluate costs and possible finantial contributions Harmonize methodologies and possibly software (Seiscomp 3. 0 offered by Germany was accepted) Start a test-phase between the RTWC pre-candidates: INGV (Italy), NOA (Greece), KOERI (Turkey), BGS (UK), IM (Portugal), CEA (France) and IGN (Spain) RTWC must have on duty sea level measurements expertise staff

National Warning Centres Regional Warning Centres recommended roles and performances roles and requirements Warning/Watch Reception and interpretation of RT seismic & sea level measurements Reception of RTWC messages Dissemination of warning and cancellation messages to national authorities according to the national response plan Monitoring tsunami propagation and update information to national authorities Determination of seismic parameters Forecasting of tsunami arrival time, amplitude and run-up for the national coastline Provision of information to other national TWCs and RTWCs Watch Reception and interpretation of RT seismic and sea-level measurements Determination of seismic parameters Forecasting of tsunami arrival times and level of alert (yellow, orange and red) at each forecasting point specified by MS Exchange seismic parameters and information with other RTWCs and NTWCs Disseminate watch and cancellation messages based on the alert-level decision matrix to NTWCs and the Tsunami Warning Focal Points Monitoring of tsunami propagation and disseminate updated information in priority tsunami amplitude measurements Above and beyond watch time National Tsunami Emergency Plan National Procedures (SOP), documentation National tsunami exercises Catalogue of inundation scenarios National tsunami data base Monthly tests of the watch system Procedures, documentation… Regional tsunami exercises Conduct training courses in collaboration with other RTWC and IOC Participate actively and report to the ICG and WGs

National Warning Centres Regional Warning Centres recommended roles and performances roles and requirements Requirements Seismic as well as tsunami/oceanographic expertise Access to Tsunami and large earthquakes data base Real-time transmission systems for reception of data Real-time alert reception system e. g. GTS, Internet… Backup/independent power supply Permanent staff on 24/7 watch Inundation modelling capacity Requirements Seismic as well as tsunami/oceanographic expertise Direct access to a tsunami and large earthquakes data base Real-time transmission systems for reception of data Real-time alert reception and transmission systems like GTS, Internet… Backup/independent power supply Permanent staff on 24/7 watch Tsunami modelling capacity
