When the Indian Ocean tsunami struck on Dec. 26, 2004, no one saw the massive waves coming. Authorities in Indonesia, where a 9.1 magnitude quake sparked the tsunami, weren't able to send out an alert because the country's sensor system had been hit by lightning. Thai officials did send a warning, but only after the first deadly wave hit. And in India, word of the disaster went to the wrong official.
A few years later, in 1949, NOAA established the. Richard H. Hagemeyer Pacific Tsunami Warning Center in. Ewa Beach, Hawaii. The West Coast/Alaska Tsunami Warning Center, in. Palmer, Alaska, was established by NOAA in 1967 as a direct. result of the great Alaska earthquake that occurred March 27, 1964. Of 132 deaths, 122 were attributed to the Pacific-wide. tsunami generated by the magnitude 9.2 earthquake.
