The Pacific Tsunami Warning System (PTWS) was put in place nearly 50 years ago by UNESCO’s Member States through its Intergovernmental Oceanographic Commission (IOC), when a 9.5 magnitude earthquake on May 22, 1960 off Chile generated a tsunami heavily affecting Hilo in Hawaii and the Sanriku coast of Japan. In the aftermath of the Indian Ocean tsunami on Dec 26, 2004, building on this experience, IOC-UNESCO has been working with its member states to establish similar systems for the Indian Ocean, the Caribbean and the seas around Europe to ensure a global cover for tsunami hazards.
