Official warnings The International Tsunami Information Centre describes where tsunami warnings originate from for most countries that are at risk from tsunami. Many countries such as New Zealand also have official warning systems that are used to warn the public. These warnings are distributed locally by emergency authorities (the Ministry of Civil Defence & Emergency Management in New Zealand) and may be delivered via siren, telephone, txt, loud hailer or other local arrangements.
