Are we in the right path in using early warning systems?

This paper focusses on the recent tsunami in Indonesia and the factors led to the mass killing. We also discussed the failure of early warning systems, steps, methods, and technologies, in general, to improve the early warning systems in the future to mitigate the loss of lives and property during these impending disasters. We believe that this paper is timely as Indonesia has seen one of the worst tsunamis in recent years and the threat is still on. Hence, we stress the importance of improving and strengthening the existing early warning systems.
