Tsunami Warning Systems: Life-Saving Technology

Early warning systems have saved countless lives, but gaps remain in coverage and communication. Blue Ocean News investigates the network of buoys, sensors, and alert systems that protect coastal communities from devastating waves.

After the 2004 Indian Ocean tsunami, nations invested billions in detection infrastructure. Yet many remote communities still lack reliable alerts, relying on traditional knowledge and word-of-mouth warnings.

This story follows the scientists maintaining deep-ocean sensors and the emergency managers who must make split-second decisions about evacuations. Modern technology combines with community resilience to create layered defense systems.
