<P> The First United Session of the Inter-governmental Coordination Group for the Tsunami Early Warning and Mitigation System in the North Eastern Atlantic, the Mediterranean and connected Seas (ICG / NEAMTWS), established by the Intergovernmental Oceanographic Commission of UNESCO Assembly during its 23rd Session in June 2005, through Resolution XXIII. 14, took place in Rome on 21 and 22 November 2005 . </P> <P> The meeting, hosted by the Government of Italy (the Italian Ministry of Foreign Affairs and the Italian Ministry for the Environment and Protection of Land and Sea), was attended by more than 150 participants from 24 countries, 13 organizations and numerous observers . </P> <P> A Caribbean - wide tsunami warning system was planned to be instituted by the year 2010, by representatives of Caribbean nations who met in Panama City in March 2008 . Panama's last major tsunami killed 4,500 people in 1882 . Barbados has said it will review or test its tsunami protocol in February 2010 as a regional pilot . </P> <P> Regional (or local) warning system centres use seismic data about nearby recent earthquakes to determine if there is a possible local threat of a tsunami . Such systems are capable of issuing warnings to the general public (via public address systems and sirens) in less than 15 minutes . Although the epicenter and moment magnitude of an underwater quake and the probable tsunami arrival times can be quickly calculated, it is almost always impossible to know whether underwater ground shifts have occurred which will result in tsunami waves . As a result, false alarms can occur with these systems, but the disruption is small, which makes sense due to the highly localised nature of these extremely quick warnings, in combination with how difficult it would be for a false alarm to affect more than a small area of the system . Real tsunamis would affect more than just a small portion . </P>
