TSUNAMI Warnings Possible Permanent Method of Promulgation Tsunami Warnings can be classified as another type of MSI alongside Nav Warnings, Met Information and SAR Information Regional Tsunami Warning Centres become authorised information providers in the International SafetyNET Service Regional Tsunami Warning Centres input warnings directly into SafetyNET (accessed through a specified LES to broadcast through the appropriate satellite) Warnings are given a distress priority (activates audible alarm on the receiver) Warnings are issued to a large specified (circular or rectangular) geographical area i.e. one broadcast reaches all relevant national points of contact 19 TSUNAMI Warnings Possible Permanent Method of Promulgation National Points of Contact activate National Contingency Plans which may include: Re-broadcasting warnings through national radio and television Direct contact with major ports and local authorities to rebroadcast information locally Broadcasting warnings to vessels in coastal areas through NAVTEX 20 10
TSUNAMI Warnings Possible Permanent Method of Promulgation Vessels at sea receiving the warning through SafetyNET or NAVTEX will consider re-broadcasting the warning on other means e.g. VHF R/T to other vessels and port authorities in their vicinity who may not have SafetyNET or NAVTEX receivers 21 TSUNAMI Warnings Possible Immediate Interim Solution Tsunami Warning Centres pass warnings to relevant NAVAREA Co-ordinators who input warnings directly into SafetyNET for broadcast within their NAVAREAs Thereafter, as for proposed permanent method 22 11
TSUNAMI Warnings Requirements in order to Implement the Immediate Interim Solution Designated Tsunami Warning Centre with reliable communications links to relevant NAVAREA Coordinators (e.g. preferably any 2 of the following: telex, e-mail, fax, telephone, radio) National Points of Contact equipped with SafetyNET receivers National Contingency Plans for onward dissemination of warnings and measures to mitigate tsunami effects 23 TSUNAMI Warnings Requirements for permanent system Designated Tsunami Warning Centre with satellite EGC equipment and secure communications links to at least 2 satellite LES National Points of Contact equipped with SafetyNET receivers National Contingency Plans for onward dissemination of warnings and measures to mitigate tsunami effects 24 12
Measures already taken IMO and IHO IMO COMSAR circular and IHO Circular Letter issued to all members facilitating the use of the WWNWS for issuing Tsunami Warnings Chairman of the IMO SafetyNET Coordinating Panel is ready to authorise Tsunami Warning Centres as Information Providers in the International SafetyNET Service 25 Measures already taken IMO and IHO IHO CPRNW is ready to liaise with IOC with respect to the format of Tsunami Warnings and updating the relevant MSI guidance documents INMARSAT Ltd (who currently manage the International SafetyNET service) are ready to provide training and advice to Regional Tsunami Warning Centres 26 13
