<P> People in some areas would have had more than adequate time to seek safety if they were aware of the impending catastrophe . The only way to effectively mitigate the impact of a tsunami is through an early warning system . Other methods such as sea walls only work for a percentage of waves, but a warning system is effective for all waves originating outside a minimum distance from the coastline . </P> <P> The Indian Ocean Tsunami Warning System was agreed to in a United Nations conference held in January 2005 in Kobe, Japan as an initial step towards an International Early Warning Programme . Nanometrics (Ottawa, Canada) and RESULTS Marine Private Limited, India, delivered and successfully installed 17 Seismic VSAT stations with 2 Central Recording Station to provide the seismic event alert to the scientists through SMS and E-mail automatically within 2 min . </P> <P> The system became active in late June 2006 following the leadership of UNESCO . It consists of 25 seismographic stations relaying information to 26 national tsunami information centers, as well as 6 Deep - ocean Assessment and Reporting of Tsunami (DART) buoys . However, UNESCO warned that further coordination between governments and methods of relaying information from the centers to the civilians at risk are required to make the system effective . </P> <P> Sensor data is processed by the U.S. Pacific Tsunami Warning Center in Hawaii and the Japan Meteorological Agency, and alerts are forwarded to threatened countries and also made available to the general public . National governments warn citizens through a variety of means, including SMS messages, radio and television broadcasts, sirens from dedicated platforms and mosque loudspeakers, and police vehicles with loudspeakers . </P>
