Hawaii residents seemed unconcerned and tourism officials have told tourists not to be alarmed by air-raid drills.
The state has dusted off its sirens which date back to the Cold War era amid growing tension with North Korea and its increasing missile tests.
The sirens will sound once every month directly after the testing of the tsunami warning system, with the call to ‘take immediate shelter. Get inside, stay inside and stay tuned.’
Residents are taking it in their stride and the Hawaii Tourist Authority says there is nothing for vacationers to feel worried about.
"Nobody in Hawaii is losing sleep over this. We feel that it’s highly, highly unlikely that something like that would happen," said HTA CEO George Szigeti.
"Not a single person has made that call to us on the North Korea situation yet," Szigeti said.
Last Friday’s test was the first since the final days of the Cold War in the early 1990s.
It comes days after the latest missile test by North Korea which has analysts fearing it could safely launch a missile with a nuclear payload.

"We believe that it is imperative that we be prepared for every disaster, and in today’s world, that includes a nuclear attack," Hawaii Gov. David Ige, adding that the chance of it actually happening is very remote.
