Hawaii has tested its nuclear warning siren just before midday on Friday Nov. 30 for the first time since the Cold War.
Some 180 sirens played on Hawaii’s most populated island of Oahu while a further 385 were heard across the state, reported the Star-Advertiser. The local paper said residents first heard the typical attention alert (used for hurricanes and tsunamis) which was followed by the new one-minute attack warning tone.
