Intergovernmental Coordination Group for the Tsunami Early Warning and Mitigation System in the North Eastern Atlantic, the Mediterranean and Connected Seas (ICG/NEAMTWS)
This document reports on the fifth session meeting held in Greece in 2008, which reviewed the progress made during the ICG/NEAMTWS intersessional period and the activities of the four Working Groups on (i) hazard assessment, risk and modelling; (ii) seismic and geophysical measurements; (iii) sea level data collection and exchange, including offshore tsunami detection and instruments; and (iv) advisory, mitigation and public awareness; and adopted updates to the NEAMTWS Implementation Plan.
It urges Member States: (i) to nominate national Tsunami Warning Focal Points (TWFP) and Tsunami National Contacts (TNC) and (ii) to openly share and exchange all tsunami-relevant real-time observational data for the purposes of the NEAMTWS in accordance with the UNESCO/IOC Oceanographic Data Exchange Policy. It also reports on decisions: (iii) for tsunami alert messages from Regional Tsunami Watch Centres (RTWCs) to use watch and advisory solely for the two classes of alert in the decision matrix while warning to be used by the National Tsunami Watch Centres (NTWCs) only; (iv) to extend the duration and mandate of the Task Team on the Regional Tsunami Warning System (RTWS) architecture until the next ICG session to prepare an RTWC operations plan for NEAMTWS; and (v) that sea level data from the NEAMTWS core network be freely available for the regional and national tsunami warning centres.
