Pacific Tsunami Warning Center

Established in 1949, the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii, provides warnings for teletsunamis to most countries in the Pacific Basin as well as to Hawaii and all other US interests in the Pacific outside of Alaska and the US West Coast. Those areas are served by the West Coast / Alaska Tsunami Warning Center (WC/ATWC) in Palmer, Alaska. PTWC is also the warning center for Hawaii's local and regional tsunamis.
