The Full Story
The first modern tsunami warning system was created in the Pacific after the deadly 1946 Aleutian Islands tsunami caused destruction as far away as Hawaii. In response, the United States established an early warning network in 1949, later known as the Pacific Tsunami Warning Center. This system used seismic data and tide gauges to detect dangerous waves and issue alerts across the Pacific basin. It became a model for tsunami warning systems around the world.
