Tsunami Warning! (English)

Pacific Tsunami Warning and Mitigation System (PTWS)
When a great undersea earthquake occurs near the coast, a destructive tsunami may result. Hitting near-by coasts in minutes, tsunami waves can travel throughout ocean basins causing damage thousands of kilometers away. The Pacific Tsunami Warning and Mitigation System (PTWS) works to quickly alert countries around the Pacific of tsunami threats. 2015 marks the 50th year of the internationally-coordinated system, which was established in 1965 after the 1960 M9.5 Chile earthquake caused a tsunami that crossed the entire Pacific killing hundreds. This fast-paced video follows the tsunami warning chain, from the natural warning (e.g. earthquake ground shaking) to the actions taken by countries, international organizations, and experts to quickly warn communities.

To sustain awareness on the dangers of tsunamis, and to educate the public on how the PTWS works to disseminate alerts on approaching tsunami, the ITIC, in cooperation with Chile, produced this 6-minute outreach video.The aim of the video is to strengthen public and stakeholder agency knowledge of, and confidence in, tsunami alerts that save lives and reduce property damage.
