Abstract:
A Tsunami Warning System must alert all persons on every vulnerable coast of imminent danger, covered by the system. The response of such a system must be rapid (as soon as possible), accurate (minimize false warning), reliable (continuous operation), effective (to save
lives). UN-ISDR Framework for effective Early Warning Systems encompass four critical linked elements (Figure 1),
• Detection, Monitoring and Warning Service (Technical Monitoring and Warning Service)
• Risk Knowledge (Awareness of the Risk)
• Dissemination and Communication (Dissemination of meaningful warnings to Persons
and Communities at Risk)
• Response Capability (Public Awareness and Preparedness to Respond)
