How many Tsunami Warning Centers are there?
The U.S. has two tsunami warning centers: the Pacific Tsunami Warning Center in HawaiĘ»i and the West Coast and Alaska Tsunami Warning Center in Alaska. The relative areas of responsibility for these two centers are explained on PTWC’s Responsibilities page. The Japan Meteorological Agency also has a well-developed tsunami warning system with multiple warning centers. Following the 2004 Indian Ocean tsunami, other warning centers have been established in Indonesia, Australia, and New Zealand. Efforts are currently underway to establish tsunami warning centers in the Caribbean and Mediterranean Seas.
