死者数がおよそ23万人にも及んだ2004年のインド洋大津波以後、
2005年1月に日本の神戸市で国連防災世界会議が開かれ、国際早期警戒プログラム (International Early Warning Programme; IEWP) へ向けた第一歩として、国連はインド洋津波警報システムを構築することを決定した[3]。これはインドネシアおよび他の影響地域向けの津波警報システムに生かされている。ただし、インドネシアのシステムは津波検知ブイが2012年に機能不全に陥った[4]ため、現在のところ津波予測は地震活動の探知による手法に限られている。2018年12月のインドネシア津波のように火山の噴火に誘発された津波を予測するシステムは存在しない。

A TSUNAMI PROTOCOL to be tested here next month will help Barbadians be better prepared to deal with natural disasters such as earthquakes. ... Harewood said Barbados was chosen as the "pilot state" for the tsunami protocol which will be discussed from February 22 to 26.
He said the objective of the protocol The Standard Operational Procedure and Communications Protocol, which has been in train for the last two years, is to provide more information on what must be done in the event of a tsunami, earthquake or any other major disaster.
"We have been nominated and we accepted the request for Barbados to be the pilot state. We have been working on this protocol for the last two years," he said.
He noted that one of the things they would be doing is adopting a general public service announcement through the Government Information Service (GIS) to help increase awareness of tsunamis."
