It is believed that the loss of human life would have been dramatically reduced, if a tsunami warning system, like the one that exists for the volcano-and-earthquake prone Pacific Rim, had been operational in the Indian Ocean. Technology, such as tremor and tidal gauges, fast data transfer and alarm mechanisms, used in combination with training ...
